Excellent experience!!!
I always feel so well taken care of by the guys at All-Star. I never go anywhere else. I tell all my friends and family. Their prices are fair and they really know what they’re doing. I don’t know anything about cars and I feel like they keep my car running well. They do everything they can to make the experience good. They have a coffee machine in their waiting room. They’re willing to take you home if you need it while the car is being worked on. it’s almost like a car repair/spa. 🤣

Great work and customer service- every time!
I really appreciate the people at All Star. They are always thorough, fair, honest, hard-working and knowledgeable. They give good advice, and make sure you’re receiving the care you ask for, and more. I have been a customer of theirs since they opened, and I’ve not gone anywhere else since.
