Brake Service
Pad replacement, rotor resurfacing, brake fluid flushes, and caliper service. We inspect your full brake system and explain exactly what your vehicle needs.
Engine Diagnostics
Check engine light on? We run full OBD-II diagnostics, pinpoint the issue, and walk you through the repair — no guesswork, no unnecessary parts.
State Inspection
Fast, thorough Maine state inspections. We'll fix what needs fixing so you pass on your re-inspection — and we'll tell you exactly what we found.
Suspension & Steering
Shocks, struts, control arms, tie rods, and wheel alignments. If your ride feels rough or your steering pulls, we'll get it sorted.
Heating & A/C
