03 / The Owner
Twenty years under the hood.
For as long as he can remember, Scott Coburn has wanted to work on cars. Twenty years of repairing vehicles — from routine oil changes to full motor and transmission swaps — took him through dealerships and small family-owned shops, every kind of job, and every kind of customer.
Something always brought him back to the automotive industry. Now, with a shop of his own, that lifelong pull comes with a promise.
"My promise to my clients is to only provide good, honest work — and to build a clientele that keeps coming back for years to come." — Scott Coburn, Owner
