Living with it

Reliability & ownership notes

  • Verify VIN, engine code, transmission, emissions equipment, and build date before ordering parts. Inspect corrosion and prior body repair, cooling and fuel systems, drivetrain originality, weather seals, electrical accessories, and modification quality.
