Emissions testing service near San Ramon, CA

I own a 2000 Porsche Boxster with 61,000 miles, so I came for the 60,000 mile service. I had an extremely positive experience at Zentrum. Three words come to mind with regard to Zentrum Motors…CUSTOMER SERVICE, HONESTY and WOKMANSHIP. Joe greeted me, sat me down and assessed my needs. I told him that I was concerned about the rib belt. I had purchased the car recently and was unsure if the rib belt had been changed. As it turned out the rib belt was good and it did not need changing They could have told me different and I would not known the difference. They replaced the spark plug coils as they were cracked. And repaired/replaced leaking sparkplug tubes among other things. The car is now running soooo good. And a gain of 3 miles per gallon is the tangible proof. From here on out only Zentrum will touch my Porsche. Robert Reed

Excellent work at a fair price. Very courteous and knowledgeable. Mike

Straightforward, patient and considerate of my ignorance when it comes to cars. Mostly interacted with Bruce, who was very helpful, but the small interactions I did have with the rest of the staff were just as nice. Reasonable prices and a very professional atmosphere. If you’ve got a Volvo (or Subaru I suppose), this is your place! Anna Nelson

Had my 1999 9-5 Saab radio remarried at this place. They did it quickly and charged a fraction of what others would have. The manager and workers were friendly and knowledgeable. Will be coming back here to get my next big repair done.

My Mercedes 2003 c240. The whole front end was busted. Conrtol arms, bushings, etc. I took it in, and the work was fantastic! My car came back clean, and running smooth! I'll be back for my shocks and hoses my car needs. I'm super happy with the service! Happy I found someone I can trust, and knows my Mercedes. YAY!
