Auto repair service near Darien, IL

Full service auto repair shop servicing all makes and models of cars and light trucks.

We are a neighborhood auto body and mechanical repair shop that looks out for our customers. We treat our customers like we would like to be treated.

I have high expectations for anyone who works on my vehicles and Rennology was up to the task. They are very professional and completed the work in a timely manner.

I have a 1992 Mercedes Benz 400E. It had been sitting a long time and was misfiring bad and the blower motor was not coming on. I already knew what was wrong when I took it to them but wanted to see what they would tell me. Talk about honest.......You will not find a more honest, reasonable, and reliable auto repair shop anywhere. They diagnosed and fixed the problems I had and the car has never run better. I highly recommend this place. Great Job guys!!

Ongoing problem for 9 years. Dealer repaired emissions error and check engine light returned in two weeks with same problem. AACCEL repaired the emissions, and now I can fuel the car in less than 15 minutes and pass the Will County emissions testing.
