Emissions testing service near Concord, CA

Excellent service very knowledgable all the stuff is very friendly . I would highly recommend them for all of your car service needs.

007 mb e350 I have been to these guys two times and both times they handled my car and service with amazing care and detail. First time was for a service check up and their price was unbeatable by anyone within a 10 to 20 miles radius. Second time my car would not start when it was cold in the morning. So I took it to them and after having a diagnostic, turned out my crankshaft sensor was no good. They fixed and teat everything and so far the car runs amazing. Will check back within a week to see if any more problems shows up. Thanks autowerk eurpean definitely my go to guys!

Next to Oil Changer and Wheel Works, opposite side of Brassdoor in side the plaza.

Came in for regular service. In and out the same day.

John is pleasant to deal with, asks pertinent questions, gives reasonable estimate as to time and cost. Delivers as promised.
