On 2/26/2026 Grandmother Susan had this to say:
JR was wonderful! He found problems and fixed them, making sure that I understood exactly what was wrong. This was not the first time to bring my car in with an issue, and once again, when I left it ran better than it ever has! Trust is everything, and JR is definitely a man who earns mine. I was very satisfied with the cost of the repairs as well.

FAQ

Do you work on both foreign and domestic vehicles?

Yes! We service all makes and models—foreign, domestic, and imports. Our technicians are trained to handle a wide range of vehicles with precision and care.

Can you build a custom exhaust system for my car?

Absolutely. We specialize in custom exhaust work tailored to your vehicle’s performance goals and sound preferences. We also offer stock replacements if you're looking for a factory-style solution.

How often should I replace my shocks and struts?

Generally, every 50,000 to 100,000 miles—but it depends on your driving habits and road conditions. If your ride feels bumpy or unstable, it’s a good idea to have them checked.

Do I need an appointment, or can I just stop by?

We recommend calling ahead to schedule an appointment, especially for diagnostics or major repairs. However, we do our best to accommodate walk-ins whenever possible.
