Diagnostic services service near Naperville, IL

I brought my car in for a diagnostic and they gave me over a quote for over $3,000 in repairs. I took it down the street for a 2nd opinion and half the things they said were wrong was a lie. Had my car repaired where I got thr and opinion for less than 1k. It's been 6 months and not a single problem. A dealership and repair shop run by conmen. Color me surprised (NOT)

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.
