"Honest and good work. Eric and his crew know their stuff and didn't pull any garbage. You could and should come here. Rare to find honest work ethics anymore."
"En route to NY from central Ohio, two days before New Year's Eve, my wife and I were filling up gas at a local station and noticed our car was leaking a ton of oil. Knowing this was not good, we called Alexander's Diagnostic and they told us come by immediately so they could take a look. Within 10 minutes, Eric and the team had the car on the lift and diagnosed that we had a broken PTO (power take off unit), which is part of the transmission. Turns out we were leaking a ton of transmission fluid and if we had continued driving on the highway, the results could have been disastrous. Eric informed us that they would need to order the part but could get it in by New Year's Eve (the next business day) and have the car fixed in time for us to drive home and be home for New Year's. As the car was still under warranty and the part was expensive, Eric encouraged us to contact Honda to see if they might have it in stock and could repair it. He was not optimistic but told us to definitely reach out to see. At no point was he pushy at all. Sure enough, the part and subsequent repair would take over a week for Honda to repair. We left the car with Eric and to conduct the repairs. As it would take two days to get the car back, Eric recommended a local hotel in the area and even offered to loan us a car to use locally while we were in town. On New Year's Eve, the part arrived, the repair was conducted, and we were able to drive the remaining 6 hours to NY with the car working perfectly. Throughout the entire process, Eric, Cheryl and the team at Alexander's were professional, honest, and hospitable."
"They were very friendly and extremely helpful and in my time of need. Worked very quickly and efficiently to get me back on the road. I very much appreciated all that they did to help my situation."
"If I could give none it would be I had the vehicle I purchased from them in the shop every day I had it they fixed issue and it came back on they sold me a piece of junk and wanted me to pay four grand and now are holding my property and my license from me I am contacting bbb and an attorney this is your shop!
