We Keep Pontiac Running

Pontiac may be a discontinued brand, but its vehicles are built on GM platforms we work on every day. That means we know the ins and outs of these systems—whether you need everyday maintenance or help solving a tough drivability issue.

We commonly service Pontiac models like:

  • G6
  • Grand Prix
  • Vibe
  • GTO
  • Bonneville
  • Montana and Aztek

Services we offer include:

  • Oil changes and fluid maintenance
  • Brake repairs and rotor replacement
  • Suspension checks and alignments
  • Battery, alternator, and starting system diagnostics
  • Engine performance testing and check engine light diagnosis
  • Cooling system and radiator service
  • Transmission inspection and fluid service

And with every visit, you’ll receive a full Digital Vehicle Inspection (DVI), complete with photos and technician notes—so you always know exactly what your Pontiac needs.

This is what reliable customer service looks like: 


"Their diagnosis was spot-on, the repairs were excellent, and the customer service was truly helpful. I feel lucky to have found them!"
