Eric Minor opened the shop more than 24 years ago with a simple idea: do honest work, charge fair prices, and treat every car — and every customer — like they matter. That hasn’t changed. Whether you’re rolling in for a tire rotation or trusting us with a six-figure build, you’ll get the same straightforward answers, the same quality work, and the same handshake when you leave.
