“Rex’s was amazing! They saved me so much money!!! I went to another shop for safety and emissions and came out with a huge list of issues wrong with my car that would have cost over $1600. After a lot of pressure to get it fixed there, I decided instead to Rex’s a shot. They were able to help me understand what was truly urgent and what wasn’t without any pressure.”

"These guys did a great job on my Jeep Cherokee. They were on-time and the quality of work was excellent. They put a new/re-manufactured engine and trans in it and also went over it front to back and fixed everything that was wrong and nothing that wasn't. I'm very satisfied."
