They were great!! They fit me in the same day and while I was there I over heard them do the same for another person. Dont know how but they did it. And so kind, I called them back because I was going to be late after they had fit me in and they let me come in anyway and they were still very nice. They were fast too. Seriously a very enjoyable trip to the Roadrunner Auto shop!!Thanks again Roadrunner!!

Take the money and run is unfortunately my experience with Brian. I asked him over the phone if he thought he could help my vehicle meet smog. I let him know at the time that we replaced one of the catalytic converters with an aftermarket, as well as O2 sensor, and was trying to fix without exceeding the cost of the vehicle. He charged me $160 to plug in his graphing code reader and tell me to replace all catalytic converters and O2 sensors with Toyota parts for a bill of $3k. Obviously I cant do this for a car worth $2k, and I already have a live data code reader. I asked him which O2 sensor was the worst (to start with that one) and he would not tell me other than all including cats. Went back home and used my reader to find the worst O2 sensor, replaced it for $40 and voila it passed. Thanks for charging me $160 to be no help whatsoever is my bad experience. Might be a different experience for those with newer vehicles or custom jobs instead of an older car near end if life.Update: I should be honest and add that the owner is correct in that the smog shop did tell me it was passing but unless I had paperwork for the rear cat, I would need to have a new one installed. I did go ahead and have a Toyota brand cat installed for that purpose. However, my 1 star rating is for the mechanic charging me $160 to plug in a graphing code reader and then tell me that the fix is to replace the entire exhaust system. And then not even tell me which o2 sensor was the worst one.

Roadrunner came well-recommended by several of my co-workers and boy were they right! Brian is a very professional and friendly mechanic/businessman. The office and waiting area was very comfortable and clean and his crew had me in and out his very well maintained shop within 20-25 minutes. They smog checked my wifes car (it passed) and they replaced one of her brake lights in a snap!We will definitely be going back for all of vehicles needs in the future.

I recommend Roadrunner because Brians honesty is impeccable he let me know that he has to buy the most cheapest parts he can possibly find from CHINA because he cant make enough money on quality parts. So if you want quality parts and bring in your own parts he will let you know that hes again not making enough money on just his labor even though the two hours he supposedly spent fixing my vehicle was more than what the dealer quoted me. It sure looks like hes making pretty good money to me he can afford to hire a secretary that cant even staple a receipt to the bill.

I always bring my cars here. They are honest, reliable, and fast. Brian is professional and knowledgeable. Its so hard to find good auto shops these days. They are also affordable which is a bonus. I highly recommend them!

Absolutely the best place to get your vehicle in tip-top shape. Knowledgeable, reasonably priced and friendly. Their work is promptly done and is always right the first time so you can rest assured that you wont be making return trips for the same issue. Brian and his crew are Top Notch!!!

Best Auto Shop in town. They get stuff done right and fast.

So I found this roadrunner on yelp. 5 star cant go wrong. So i reached out and right away I got a response to have my car serviced. Unfortunate for me . I would have to have my check engine light checked out befor my smog. But thank goodness for people like Brian. He updated me on what needs to happen and how much. I eas very pleased on how well and smothly everything went. I get to go back and get my vehicle smog. Salt of the earth family man and father and boss. I would recommend his services to anyone.

Outstanding! Great service! Wonderful staff!

Absolutely the BEST place to take your car or truck in Nevada County! Brian knows cars and is ASE Certified, so you know that he stays up on new automotive technology.

Next day appointment. Super fast and friendly!

It is so rare in this day and age to find a company and owner who understand what customer service and quality repairs are all about. Brian went out of his way to help me save money on my smog check by taking the time to go on-line and find the parts I needed and suggestions from his experience about how to do the repairs preparatory to my smog check. That alone saved me over $300 in parts and labor!I cant say enough good things about Roadrunner. I would recommend them to anyone who asked; confident they would have a great experience. g

Brian is an honest technician and very professional. He has a very nice clean, professional shop and is very courteous. And cars get fixed correctly the 1st time.

Got my car smogged here recently. They were on time with my appointment, had a comfortable waiting room, and I was in and out within 20 minutes. Great service!

Over priced. They wanted over 300 dollars for something the dealership did for less than half. They offered to sell me a battery for more than the auto parts store sells them. I paid 130 for diagnosis and 60 for an oil change that both took place in the hour they had my truck. I spent almost three thousand with them last year and I’m wondering how much of that was over charging.

I have used Roadrunner automotive on and off for years. Im not even in state anymore and i find myself calling Bryan for advice still to this day, because he is honest and competent. I really appreciate him, for always being there. Thank you very much .

Very clean shop and efficient. They remembered to place sticker in the windshield for my next oil change and the last time I had my oil changed at a different place, the did not. Very fair price.

Very very clean place, and a very clean waiting room. It was obvious to me in first 5 minutes these guys know what theyre doing. And also, I have to add that theyre quite honest. Kept me from making a expensive mistake on my truck. This is the place Im always going to go from now on for my American vehicles.

Such a friendly and competent shop! I recommend Roadrunner for their great service, comfortable waiting room, good prices and courtesy. Thanks, Roadrunner for getting my service done so quickly and smoothly!

My first visit for a smog check. Brian is very nice and friendly. One of the best and clean shops in the area.Very professional. I do recommend this shop.

I live in Nevada and my truck broke down on my way to CA. Roadrunner was recommended by a friend and my tow service got it there about 730 at night. By 815 the following morning, Brian had an initial diagnosis on it but was swamped with already ongoing work & told me he couldnt get to it till Monday. I had business in the area so not a big deal. Monday morning he called me with a full diagnosis that was a much happier outcome then Friday and by 230 Monday afternoon had me back on the road! I cannot praise this place highly enough, kind, professional, honest, quick service. If I lived in the area, they would be my full time shop.

Had a dead battery..called in day before and battery was there ready to be installed after I got jump started . Did oil change at same time ..in and out in around an hour.

Great and reliable service! Highly recommend

I got an appointment the next day from calling. They had me in and out in about 20 minutes.

Satisfied customer, quick and friendly servicePleasantly surprised by the quick service, knowledge and friendly service. I selected this place on line with no referrals or experience of Roadrunner Automotive. I was satisfied and would return. I also love the dog friendly atmosphere where the family pug who was soaking up the sun on the floor mat greeted you when you entered the place.

Very quick smog test. Will be bringing my car back for an oil change.

Quick Appointment. Quick turn around. Comfortable waiting area. Good prices.

Ive been to Roadrunner twice, and both times the service has been great, the work excellent, and the price very reasonable. We had taken the car to a local dealer because a warning light had come on, and the dealer suggested some very expensive repairs that ended up not being the real reason for the light. Brian was able to diagnose the real issue and fix it, as well as do additional work we needed for a lot less than what the dealer wanted. Most important is the fact that hes honest and straightforward, and being able to trust your mechanic is everything. Highly recommended.

Superior Customer Service!!! Brian is very friendly, personable and honest. He was fast, efficient and fair. The shop is very clean and well organized. Brian goes above and beyond to help make the process of car repair as easy as possible. I highly recommend Roadrunner Automotive to anyone who is in need of a great mechanic!

I was referred to Brian at Roadrunner Automotive by Bob at Karls Smog and Repair.Brian did what was required to make sure that my car would pass the smog test when I took it back to Bob.While I was at Roadrunner Automotive, I told Brian that my car, a 2006 Nissan Altima with 123,000 miles, was making noises and that the steering wheel vibrated badly when I applied the brakes. Since I know nothing about cars, I told Brian that I would have to rely on his expertise. He put the car on the rack and told me exactly what the problems were. I needed brakes, front and rear, the left front wheel bearing needed replacement and several other items needed to be fixed. Brian did everything that was needed at a very reasonable price.I was very impressed with Brians knowledge and his commitment to make sure that all of the necessary repairs were done to make my car safe to drive. I also appreciated that he explained everything to me in a way that I could understand. He did not try to sell me anything that was not needed. I had confidence in him, and I knew that he was a person of integrity who could be trusted to do what was right for me..I would strongly recommend Roadrunner to everyone who wants to get their car repaired by an honest, reliable and reasonable mechanic. Brian is NUMBER ONE in my book.I would also tell anyone who needs to get a smog check to go to Bob at Karls Smog and Repair; he is the GREATEST.

The best service, and honest mechanics. I had a quote from roadrunner and it was about $400 less than the local Ford dealership. They do amazing work and are honest and fair. They are ford certified mechanics for a lot less.. wonderful place and also have a cute fur baby mascot:)

Would highly recommend Roadrunner Automotive to everyone. Whether you need your car serviced or need a smog, you should definitely give them a call. You will receive great customer service and a friendly greeting from their pug “Lilly”.

Knowledgeable, friendly, fair and ETHICAL! Ive come to realize that you do indeed get what you pay for, so when shops have good reputations and price is close, service and people win. Roadrunner has the best people, fair and honest, they straight shoot you, not trying to oversell you anything you dont need. Will continue going for routine maintenance as well as the oopsies, highly recommend them! Oh, and when you use a credit/debit card a portion of those fees are getting donated to a local charity!

Just moved here and Roadrunner was recommended by a coworker. So glad he led me to them. I feel I can trust the repairs they recommend and they are always on budget and schedule.

Needed smog check for my car and found Roadrunner with a google search. Drove over, at about lunch time no less, and the owner managed to scrunch me in before the next appointment. Professional and courteous in the bargain. Highly recommended, based on my experience.

We have taken several of our vehicles to Roadrunner Automotive for service and repair. Brian, the owner of Roadrunner Automotive, is extremely knowledgeable and focused on getting the job done right the first time. We especially appreciate his skill at diagnosing and troubleshooting errant problems that crop up on our vehicles from time to time. Weve recommended him to friends and have heard only positive reviews back. In short, Roadrunner Automotive does a good job and is also fast and affordable.

If someone is looking to purchase a vehicle I highly recommend this place, he definatly is honest and trustworthy. My daughter bought a car from him a few days ago & he was trying to find something out about the vehicle, that was working earlier before we came but all of a sudden stopped. he worked on it for about 2 hrs and while we waited he took me and my 2 daughters across the street & bought us all lunch. But that isn’t it he told us once we drive home from San Leandro to Fairfield the battery should charge and problem fixed however once we got back it wasn’t fixed. I notified him and instead of him saying sorry“sold as is” He told us to take car to his michanic and not worry about the cost he would take care of it so today that is what we did. Michanic worked on car for about 3-4 hours and fixed everything we did not have to pay a dime. The gentleman at roadrunner automotive took care of everything. To me this is going far and beyond what this man was required to do considering once the car is taken off the lot it is sold as it. I’ve also read other good reviews on this man and I would highly highly recommend this place to anyone who is looking for a used car.

Great service. Called in the morning for a smog check at 10:30 and got right in. They were finished before I got settled in! Professional, friendly service

Excellent service and competitive prices. Honest and experienced ownership. I dont plan on taking my mustang anywhere else.

Quick smog service at a good price!

I am so glad that I discovered Roadrunner Automotive. Making an appointment was easy and fast and the service was done while I waited in their very comfortable and clean waiting area. It is conveniently located too. It is very professional. It will be my “go to” shop for any of my automotive needs.

Ther fast friendly and a pleasure to do bussiness with. Great people

I needed a same day smog, and these guys were able to handle me without any issue. The price was right, and the service was prompt.

I took my Titan to Roadrunner Automotive for a Smog check. The staff was courteous, friendly and knowledgeable. I highly recommend their shop.

Always a pleased 😀

The owner is a great business person . Hes friendly and anserws questions in a positive, knowledgeable way that doesnt make a person (a woman) feel uneducated or belittled about a vehicle, which is hard to find in todays society. The people who work for him also have a pleasent attitude and genuinely care about the customer. Their work is of the best quality and done in a very reasonable time. I am happy with what they have done for my vehicle, I will be a return customer and recommend them for anyones vehicle problems. Im glad that I came across this place and these people last winter. Thanks Roadrunner for being honest and trustworthy cause knowing you did the work right took alot of worry off my vehicle stress. 😊
