    I came in two weeks ago for an oil change and tire rotation with Rob and Geoff. Geoff probably saved my life by telling me I needed to get new tires ASAP....read more

If a comfortable waiting room is your priority, this is not the repair shop for you. But if you are like most customers, and want excellent work at reasonable prices, then you don't need to read any more reviews. More important than the work is dealing with an honest auto shop. Geoff has done both major and minor work on my Toyota to my complete satisfaction. I have also emailed Geoff for quotes, discuss problems, and suggestions about my car. What other repair shop can you do that?

Geoff is a great mechanic. He's personable and have great attention to detail. I've brought both my 1997 Corolla and 2009 Honda Pilot to him for repair/maintenance and i will not take it elsewhere. Other places may charge you $$$'s more, this place will charge you with an hoest price and $$$'s less than other shops.

good stuff

I come here a lot for all my automotive needs. Geoff has helped me with my mercedes cls, bmw m3, infiniti fx45, nissan 350z, and Mercedes ML (yes i have a problem). He usually hooks me up with good prices and has every tool in the book. i will be sure to come here for future maintenance or issues.
