Diagnostic services service near Walnut Creek, CA

I took in my 2007 Nissan Murano because the dealership said I had both exhaust manifolds cracked and leaking. Niki and his team discovered that I really only needed one replaced and the other would be fine for a few more years. This saved me a lot of money and I never would have known the difference! I appreciate the honesty. The other thing to mention was that they ran into some issues with the replacement because the old one was so beat up. Niki said it would take another day to complete, but I was going out of town with my family. He and one of his mechanics worked extra hard and got it done in time. Very good service! -Patrick Naylon

I brought in my 1987 Dodge B150 van. Yes, a really old van that wouldn't pass smog. A "gross polluter" per the smog shop. Michele and Dennis worked on my car diligently to figure out what the issue was. Turns out the timing was way off. After 2nd smog test, the van no.'s were really good to a low emissions vehicle. Yeah! Dennis also pointed out that my steering column was very loose. In the past, I've been told that the whole steering column needs to be replaced. But here at GF Automotive, it might be repaired, saving me a whole lot of money. GF is an honest auto mechanic shop. Hard to come by these days. Thank you Michele and Dennis for all your help!

Great team and excellent service at R&I. Rey has has been our family's mechanic for years and I wouldn't go anywhere else. Gabe Overbay

Honest mechanics with great customer service. Steven took the time to call me and explained to me the condition of my brakes and he called again when the work was completed. i work close by and it is convenient for me to pick up my car after hours at the AMPM store. Fair prices and honest mechanic.

Holland Car Care is consistently friendly and competent. I used to take my BMW to the local BMW dealership for maintenance, but I switched to Holland Car Care years ago and intend to stay with them forever. Nice and welcoming staff; great online scheduling. Very reliable. Never upselling. Kudos.
