“Today I went in to three Star Auto for an alignment. Immediately after entering i was greeted and offered a drink and snack, I felt very welcome. Everyone i talked to was very friendly and easy going. the mechanic Tim was more than happy to take me into the bay and show me what he was working on and explain an issue to me. Not only did he do an exceptional job but he did it for a great price to which is rare in this industry.”
