"Don't let their terrible phone etiquette scare you away. These folks are the bee's knees! I have never been so happy with an auto service company in my life. Btw, they don't talk like that in person. Face to face they are perfectly polite, not sure what causes the diffrence. ANYWHO...Their repairs are lightning fast, done correctly, and so cheep you would swear they are saints. They don't work weekends, which is a bummer; but hey, everyone needs time off! Just be aware that they only service asian car brands."
"I don't know these guys, but have to say popping up on Google when anyone looks for Summit Racing hasn't hurt business at all has it? I'm dying here..lolol."
"Took my saab there and they told me they couldn't figure out what the problem was. Well I did! It was a loose fuse that I found myself. Customer service was terrible. Will never go back there again."
"I've been going here for a few years. First with a 1996 Honda Accord. Now with a 2000 Toyota Camry. Marc and Jane are straight shooters who don't try to sell anything. They only advise on what you need. Sometimes I make the mistake of trying to get "cheaper" repairs elsewhere, but often find myself going to Summit Auto to get them corrected. I just setup another appointment for that very same mistake. I won't be doing that again. To date, I haven't had any recurring issues after having my car serviced here and I drive vehicles with high mileage. It's not easy to find fair and honest people these days. Summit Auto is one of the good guys!"
"First time having Car Serviced. They do great work and in a timely manner. No COMPLAINTS👍👍👍"
