“All the staff are great. They were honest about my brake repairs and provided options for me. Letting me know that I would be safe driving a few more miles before needing to replace all 4.
Craig said the would inspect a vehicle that I was look it to purchase. Not only did they let me know what items they can repair on the vehicle, they looked up how much it would be to repair the things that showed up with issues.
I would highly recommend them to anyone looking for a trustworthy and capable auto repair shop”
