My catalytic converter was stolen for the second time in 6 months. I called many repair shops and the quotes were very high. 4G gave me an excellent deal much lower than the other quotes. They finished the job in a timely manner and were very friendly and professional. I will call them the next time I need car repair. I highly recommend 4G.

I was driving through, from Kansas and stopped at Auto Zone for a diagnostic check, because my car was acting up. They referred me here, when I asked for a fair and reliable mechanic. They diagnosed my car and were fast and professional and really nice. It made me very thankful! It’s rare! Thanks!

I had two other repair shops tell me I needed to see a transmission specialist for a leaking transmission, so I made the appointment with 4G letting them know of what the prior shops said. To my surprise- Boni let me know the leak was very bad an oil leak, but less costly then the aforementioned transmission leak would have been, and no transmission leak was apparent. If he wanted to he could have lied and said I needed both repairs and I would have believed him. Or he could have just sold me the transmission repair (and fix the oil leak on the down low) and I would have paid much more, but not known the difference. But instead he took me back to the shop and showed me the leak, showed me the difference between how oil versus transmission fluid looks. He completed the oil leak repair in one day and I had my car back. I was absolutely impressed by the affordability, Boni’s knowledge, honesty and integrity. As a woman who doesn’t know a lot about cars- you can’t help but feel Mechanics like to take advantage of you and your bank account. I am glad I found a shop and person I can trust! I would highly recommend this shop to anyone in need of car repairs (big and small).

Extremely thankful! Long story short: In the moment of dispare I googled the nearest auto shop, 4G automotive was the closest one to me. Not knowing what to expect I based my decision off of recent customer reviews and a quick phone call. I managed to get my car into their driveway and no more than 30min my car was as good as new, now on my way back to California! Thanks guys

I am very happy with the service provided at this location. Got a pretty bad oil leak and coolant leak repaired and also the Turbocharger replaced on a 2013 BMW a few months ago. The person who owns the shop is a nice guy as well.

I brought them a used transmission to be installed in my Jeep Srt8. They got it done on time but they claimed the transmission was bad because it slipped all the gears. I then took it to another shop and found out the transmission was very low on oil. Worked perfect after adding more oil.

Very helpful and very professional! They do great work for a very good price!

They get it right.KnowledgeableNice smiles allAround

Honest, fast, and reasonable pricing! These guys are awesome got my truck back on the road the same day. Definitely would recommend!!!!

Simply the best, theyve a very nice customer service, the price is really good, the work was done in time and I didnt pay extra fees. Highly recommend.

I definitely recommend 4G Automotive! They were so nice, friendly & honest. And didn’t charge an arm & a leg.I was coming through Aurora in May headed to Estes Park from Kansas when my breaks started malfunctioning. I googled mechanics in Aurora and had initially chosen another mechanic shop close by & they were wanting to charge me $500. (They did that thing where they try to charge you more for things that your car doesn’t need, usually done when you’re a woman or when they think you know nothing about vehicles. On top of that the people at this other shop were very condescending & rude.) I decided to go else where and nearby was 4G automotive. Best decision! The guy at the front desk was very nice. They charged me what I think was a fair price & got the job done the same day. Thank you so much!

Received an excellent diagnostic and totally fixed my car. Very trust worthy work and fast.

On 12/1/20 I found myself needing a reliable and trustworthy mechanic. Well, I found one with 4G! I am very pleased with the great quality and timely service I received at 4G, I’m recommending my family and friends. This is the kind of business that I like to support.

Professional job, on time, best price. Very knowledgeable. Reviewed price before work was done. No surprises. Very professional.

Boniek Was AWESOME!!!!! Got me a last minute appointment, was super informed and helpful. Definitely will be back !

Honesty and integrity, two words that are often overlooked in this industry. These guys got both and more. Boni the owner is a real nice guy and has won me over as a lifetime customer. Their prices are more than reasonable and they are quick with what they do. We moved here from Seattle and Im glad we have found ourselves a new shop to trust here in town.

4G is the best in town. I highly recommend this place. Their honesty is the best attribute they have. I also love the personal attention by the owners.

I brought my car here last minute in the afternoon because my car stopped working at a stop light. Boni was incredibly professional and nice! He took my car in even though they were all booked up for the day. He let me know he would work on my car the next day. I was more than happy with that and went home. A couple hours later Boni gave me a call and said he squeezed in a moment that day to look into my car and he gave me a quote over the phone. The whole time my car was at his shop, I felt valued as a customer and the communication was amazing. Great shop, thorough and quality work. I would recommend this place to anyone.

I have been using Gracia auto repair for over 10 years. They used to fix a fleet of my trucks always did an excellent job. Now I still take my personal vehicles to him because he takes care of us on the price and we have a great relationship. He does fantastic work and he always honors his warranties.

My truck had a electrical problem that even the dealership couldn’t diagnose, they found the issue with my truck and got my truck fixed right away. Thanks for your help! Highly recommended.

4G is the greatest place to take your car

I found these guys through Google and decided to take my car to them because of the reviews. I found my new mechanic, even though I got bad news of a blown motor... They diagnosed my car quickly and called with my options. They were understanding when I didnt want to do anything to fix it and didnt try to push me to, they also did the diagnose free of charge. Even though this experience with them was short lived, I will be bringing my cars here and recommending them. They could of easily given me the bad news and still charged me 50 something dollars for the diagnose and tried to talk me into the motor replacement or whatever, but instead agreed with me on that it wasnt worth doing and were straight forward about it. Finally found a good honest mechanic.

Here you can find that which is so difficult to get, HONEST, THEY ARE REALLY GOOD, TRANSMISSION SPECIAKIST. Otherwise they make the most of mechanics you can need. Fair prices and good service

4G was prompt and attentive to my needs. I highly reccomend supporting this business!

Excellent Place they are really good on their work and give me great service and warranty

This is a really good place to take your car, he is honest and do a great job, I really will be back if have any trouble

I love this place they always take care for me!!

I just moved here and had car problems with my old truck. Pick Gracias just to try and get it fixed.... end result was it was a new engine that would be needed. But they check it out and had my car there for two days till I scrapped it. He did not charge me a penny! Up front and accomadating will go back for any future needs!

Good service, and nice people!!

First Time Going Here... Staff Friendly.. Does Great Work For Reasonable Price.

I brought my truck for a noise and they told me there where just the brakes, Im a girl and I do not know nothing about cars, they give me really good price and fix my truck fast, if I got any other problem I will bring it back to them

Excelente atención que tienen a los clientes te explican todo muy bien y de Buena manera lleve mi auto a un chequeo y te hablan con la verdad no me hicieron gastar en algo que no necesitaba lo recomiendo 100% excelente servicio

The truth is, I, Jaqueline, recommend them, I am very satisfied with the work that my car is looking for, they arranged the Transmission and it was very good, I did not have problems and they are very professional, responsible do not look for another place this is the right one ...

Excellent service and quality, reliable in every way, and very honest when evaluating the problem of my car.
