"I own a Subaru Forester and needed some scheduled maintenance plus a repair of my driver window. I first asked Stiver's Subaru for a quote while I already there taking care of a recall notice. I was quoted about $1500 for what I needed. Considering the largest cost was the scheduled preventative maintenance, I was completely flabbergasted. I even considered, however fleetingly, that maybe I should just sell my car because it was insane that this would cost roughly 25+% of my car's current total value. I came across Summit because it was highly recommended by my neighbors. I gave them a call, said what I needed, and Jane replied "Yeah, that's an expensive one." I cringed, but then she quoted me about $500 for the service. The window would be a mystery until they looked at it. It turned out to be a broken motor and they had to order the part, but all in, it cost me $750 dollars. Yeah, that's literally half of Stiver's. I'm not sure if Stiver's uses gold-plated unicorn-crafted parts or what, but I'm overjoyed with the service I received at Summit. Jane was always informative in telling me what was going on with my car and she managed to do so without either inflating everything to seem dire (ie. expensive) or being condescending. The after-hours dropbox for keys was incredibly convenient so I didn't have to beat morning traffic to get my car there. The receipt was itemized and in plain language to tell me exactly what was done. The shop was an easy walk from the Avondale MARTA station so I could pick it up right after work. This was the most painless experience I could have asked for. I'll definitely be a returning customer."
"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!"
