Store Reviews

Erika T

I have been bringing my cars here for 15 years, and they have always always provided excellent service at reasonable prices. I've never felt taken advantage of or been pushed to buy something I didn't need. They are always willing to show you a problem and explain things. Today, they really made my day. My battery died at the gas station, second time in 2 days, so it was time for a new one. I got a jump start and headed straight over, expecting to sit and wait a few hours. I was in and out with a brand new battery in a half hour. Bonus points for free wifi with a good enough signal that I could work remotely from the waiting room on my laptop. Thank you, Sullivan Tire! 8/21/2018
