This is the place I will return again and again! I am very impressed on how they handle the entire process of my car trouble. I was changing out my drive belt and ac belt, not only their price was more than reasonable but their work was spot on! I was able to get in and out fast. Also ask for an oil change while I’m there and it was not a long wait at all! They were upfront about the cost and give me a detailed break down. They also warned me about taxes and fees that may apply later at check out. No hidden cost that will surprise you later. Overall, I am very pleased with my service and I will return with both my cars for any service needs. Thank you RC auto for taking care of my car! Ben Chang

Just got a few suspension related stuff fixed at BTM and the folks at BTM Mike and Brad did a fantastic job on the car. At 160k, my bimmeer runs like a brand new one. keep up the good work guys.. -Murthy

Brian very patiently and expertly diagnosed the reason for my engine suddenly shutting down for apparently no reason.

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!
