F1 Auto Diagnostic And Repair 2110 North Stone Avenue, Tucson, AZ 85705

"Mark knows his stuff and solves problems. He couldn't book me an appt fast enough so he took the time to troubleshoot with me over the phone, even following back up after having done more research. That's how you earn loyal customers."

"It is the greatest shop ever. Actually, I went to 4 other shops before coming there. They all requires 50-60$ to just diagnosing the problem which I already knew and wanted to know repair fee. Marc diagnosed my car without asking any charge and offered very affordable repair. Even after fixing my car, he told me other issues in my car he observed while he was driving."

"Completely lacking in even basic knowledge, the owner is a total liar and scammer"

"This guy will waste your time and have the nerve to charge you for basically doing nothing. He kept my car for over 24 hours to tell me a simple diagnostic. Scam artist! Its no wonder he has a garage full of peoples cars he cant fix!"

"This is a hidden gem. Mark Ginsburg and F1 are amazing. Hole in the wall place, but their technical expertise is top shelf. I had a problem after I bought a used truck and found air bags missing and a control module bypass. Mark was recommended to me by my favorite body shop. He laid out what could be wrong besides the missing airbags, gave me a high and a low price. I took my truck and the replacement air bags I bought to him. They installed them within the price range. Mark hooked up one of his many diagnostic scanners and showed me the airbags and the control module were working without errors. He didn't have to go that far and I can promise you no dealer would ever take the time to do this. Mark is as honest as the day is long. He's a rare bread"
