Emissions testing service near Castro Valley, 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
