They know their stuff! I had a very complex AC issue that involved wiring, the cars computer, a non-standard sensor and a compressor from another model of car. Tachyon was the forth shop to attempt this repair and the shop that fixed it. After some conversation with the owner this has become the only place I will take my car. I highly recommend!

Extremely knowledgeable staff, always high quality work performed. Been coming to tachyon for over 15 years and wont go anywhere else. 100% recommend.

I’ve taken my cars here for many years. They’ve always been up front about repairs and preventative measures. They really stepped up recently when we went in for an oil change right before a road trip. The rear brakes were bad and they got the parts as fast as they could so we could have a safe trip. Their crew is awesome!

These guys are the best. I’m almost hesitant to write this review because I don’t want the secret to get out, but they deserve all the praise. They are the most honest, fair, knowledgeable mechanics in town. They have worked on my last 2 cars and they take care of me every time. If you want an honest mechanic that is super affordable and knows their stuff, tachyon is your place! No fancy waiting rooms or loaner vehicles that would need to be paid for by jacking your prices up. Just badass, hardworking mechanics that seem to be few and far between these days. I feel like tipping when I pickup my car.

Great experience with both of my cars. Highly recommend especially with the quick turnaround

Chaz and his crew are fair and honest. They do a great job!

Great shop. Super reasonable prices. Fantastic for imports.

They are always professional, quick, and honest. Take a look outside at the cars they drive, this isnt a chain store where people go for a check, they enjoy doing what they do.

This place is awesome if you want quality, honest work done on your car. Cant be beat.

Been taking my car to Tachyon for a couple years, never had such a great customer service experience before. Guys that work down there are great and never fail to take care of me and make things right. Would recommend Tachyon to anyone in need of any type of service work. Great work and great pricing.

I had a good experience at Tachyon yesterday -- took in my car that had already been looked at by two other shops in Louisville, neither one could accurately diagnose the problem. Tachyon had it for an hour, charged me a reasonable fee for a proper and thorough diagnostic, and figured out the issue -- now its up and running smoothly again. Ill be taking my cars there in the future when any issues pop up.

Haven’t even got into the place and it’s like they don’t want my business. Called once to get quote and was told I would get a call back and never did. Called multiple more times the next day and couldn’t get an answer, called off my work phone and they immediately answered the phone. Got a price and told the man I would like to bring it in Monday and asked if I need an appointment, he told me no they are quite slow this time of year and it shouldn’t be a problem. Just called early Monday morning (my only day off till next week) and was told they are to booked today and it’s appointment only... the price they quoted me is great but I have the impression they have no interest helping me get my after market exhaust installed.

Love this shop. They know how to make you feel welcome and the shop dog is really cool. They are extremely knowledgeable and trustworthy. Its definitely the only shop I will be taking my vehicles and its the only shop I recommend to friends and family.

Had a great time working with these guys. They did everything i needed for my exhaust and then some. They were a little stand offish but dont let that discourage you. The price was wonderful for the work they did and they worked very well with my schedule. I will continue to use them for all my vehicle exhausts from now on.Thanks guys

I was recommended by a friend and was really thank for their fast and efficient service. It was also decently priced and they were all super friendly. Great job guys!!

My Old Man and I live about an hour and a half outside of Louisville, and happily make the commute to Tachyon, because its worth it. Theyve saved us so much time, money and headache caring for our aging Lexus and Subaru over the years, and have always done an awesome job of keeping us safe and road-ready for an exceedingly fair price! Thank you guys!!!

Used this place for a pre purchase inspection, they had one of the best prices around for is and did a great job. They found a few things that needed to be worked on after purchase their total price for replacing the timing belt and water pump, plus machining and replacing the head gaskets was the same price some places wanted for doing just one of those things. Also, they had a shop dog in the waiting area and that was pretty cool. Overall this a great no-nonsense mechanic.

Ive used Tachyon for about 7 years. They always do a good job on my older imports. They keep my cars running, give me honest advice and do repairs for a fair price. They do get busy at times and sometimes a job will take longer than i would like, but I dont mind waiting since its always done well. I recommend this place to all my friends.

These guys have saved me from so many car disasters that I have lost count. I buy cheap, ancient imports and Tachyon is my secret weapon. They insist on looking over any car before I buy and telling me to get it or not. Over the course of doing business for close to two decades, they have always kept their word and done me right. Also, they like to make things go fast.

These guys are great. I called in to schedule an appointment and dropped my car off on a Friday morning. After diagnosing the problem I got a call and the quote to fix it was a little more than I expected but I am a lawyer and not a mechanic. After breaking down the parts and labor by an agent of this shop the quote made a lot of sense. They fixed my car the same day and I picked it up late Friday evening. When I went to pay, they charged me less than the quoted amount and they had actually done more exploratory work than I initially asked them to do and requested to be performed after authorizing the repairs. So I paid less than quoted and got more work done. Doesnt always work that way. A shop that is honest and performs quality work is a diamond in the rough. Other shops will quote you less than they will and if you dont care about having confidence of being able to get to work then by all means go else where. Otherwise go to them because they live and breathe mechanical work. Some moron rated them with 1 star but you will always have someone like that looking to crap on someones reputation.

Very professional. Did the work I asked of them and didnt attempt to upsell.

Had one of the best known NAME German car dealers in town quote my wife $4600.00 in needed repairs. Tachyon did it for $800.00. Turns out it didnt need what the NAME Dealer said after all. HMMM They have helped us for years. HONEST...FAIR...and...They Truly CARE :-) Best in Louisville

Wouldnt trust my cars to anyone else. Ive known these guys for years and they can be gruff because they dont suffer fools lightly. They know more about imports than anyone in town, so drop off your car, trust that theyre not trying to screw anyone over, and pay the bill on time. You can get hosed by a really friendly dealership, or deal with reasonably priced local business that is hires people who know cars rather than those who can fake smiles.

Honest shop. Great prices!

Worst garage ever, i brought my car in for an o2 sensor, they fixed the o2 sensor but also charge me for changing my oil WITHOUT ME ASKING, then when i tried to tell them they needed to take that off the ticket they got very very rude with me. They held my car and wouldnt give it back until i paid them for something i never asked them to do. I will never come here again.

The guys at Tachyon are fantastic! Always super helpful and really know what they are doing. If you want the best go to Tachyon.

I appreciate the great service Tachyon Performance. Fantastic work!!

USE THIS SHOP. Seriously, I will never take my car elsewhere. I had a friend recommend this shop to me and have been using them for about two years now and they continue to gain my trust. They are professional and knowledgeable. The guys have a polite way of being know-it-alls and I absolutely respect this attitude because they know what they are doing and they do it very well, and affordably. I always had a distrust for auto mechanics in the past but Tachyon has changed that for me, I always leave with my hands smelling like their giant shop-dog, a smile on my face, and a perfectly tuned automobile.

Unparalleled service and experience. Highly recommended!

The ONLY place I will take my car to Tachyon for repairs and oil changes. I was quoted $7,000.00 for a repair at SPRINGDALE AUTOMOTIVE - I towed my car to Tachyon and paid $1,700. and I TRUST them and recommend them to anyone with a European car.

One of the few shops in Louisville that I really trust with my car with everything from an oil chance to an engine swap. These place employs several technicians, all of whom are very experienced, especially with imports.

I couldnt believe the quality of work that was produced. Im really tough to please from the get-go and this shop far exceeded my expectations. I gave them a car that was half taken apart that I couldnt finish and they made it work beautifully.I gave them a laundry list of items and questions and a lot of back and forth and they took my phone calls when they were available and answered my questions whenever I needed.They did a custom exhaust and a custom gauge pod that replaced my ashtray and it looks so good most of my friends and family assumed that it came with it from the factory, they matched the grain perfectly using some crazy technology but the results were superb. Cant wait to bring my Miata up there to see what they can do!

These guys had fair prices and fixed my issue quickly.

Outstanding service and people. They do it all. I have four cars and they help all of them and my family, always.

So i was a bit hesitant to bring my car to Tachyon due to a couple bad reviews here and there but there were also some pretty good ones and i needed someone quick. They were able to look at my car quickly but thats where the good stopped. They actually broke a part on my car while trying to fix what I brought it in for, then they tried saying it was like that when i brought it in when i know for a fact it wasnt. they said they would fix it but they were going to have to charge for it. They also charge WAY more than most other garages around. I tried nicely asking them to fix what they broke and they refused. I wound up having to pay for something they broke. It gets worse. after they fixed my initial issue, i started to drive it home and it broke again, i brought it back and told them it was broke again and they said they could look at it again but it would cost me for them to look at it... What?!?!Save yourself some money and some headaches and dont use these guys.

I have been going there for over 10 years for a reason because they are the best in Louisville.

I took my sons 2012 VW Jetta GLI there for a second time. The first repair went very well. The second time was for a different repair. They researched it and told me that VW had extended the warranty for that particular problem and that I should take it to the dealer. And they didnt even charge me. I was very impressed and very appreciative!

Chas and the crew at Tachyon really know their stuff and they dont bullshit you like other shops do. I take ALL my imports here.

Great service, fast, & friendly! They really know what theyre doing!!!

Great shop. Super awesome dudes.

In my opinion, I felt ripped off and spoken down to and insulted on the phone. Very unpleasant experience and items on bill were shocking because they hadnt been discussed. This is only my opinion so take your chances if you want to.

Chris at tachyon is awesome, fast, to the point and does great work! !!!!

Great Work Great people and fair pricing!!

This damn place sucks they have had my car for two months just to rebuild a motor. they have lied to me 4 times and no one knows whats going on

Best in town. Hands down.TNB
