The M45 Advantage

We're not a quick-lube chain or a generic garage. We're Subaru people — and we've built the shop to prove it.

In-House Machine Shop

Most shops outsource machine work — we don't. Our fully equipped in-house machine shop means faster turnarounds, tighter tolerances, and no third-party markups on your engine work.

ASE Certified Technicians

Our team holds ASE Master Technician certifications and brings over 50 years of combined Subaru-specific experience. We've seen every failure mode — and we know exactly how to fix it.

COBB & Ecutek Tuning

Two COBB Certified Protuners with 20+ years combined tuning experience, EFI University graduates, and a Mustang Dynamometer MD-AWD-150 in-house. Real tuning, not cookie-cutter maps.

Loaner Vehicles Available

Don't rearrange your life around your car's service. We offer loaner vehicles so you can keep moving while we handle the work.

2-Year Warranty

We stand behind our work — every repair and service carries a 2-year warranty. That's the confidence that comes from doing it right the first time.

Free Second Opinions

If another shop gave you an estimate that doesn't feel right, bring it to us. No charge, no pressure — just an honest assessment from people who know Subarus.
