Customer Testimonials
Sienna AlexandraI brought in my 89 4Runner for suspension and brake repairs, and had it back in my possession by 5pm on the same day! I don’t like to take my classic vehicles anywhere but here.It wasn’t cheap but they worked with me on the price and even offered a payment plan because I was a new mom at the time. Had an overall great experience. Everyone was nice, especially the girls in the office.
