Living with it

Reliability & ownership notes

  • Follow the brochure's 4,000-mile or four-month engine-oil interval and 36,000-mile or three-year major chassis-lubrication interval.
  • Confirm whether the car has the standard 429 or optional 460 before ordering engine parts.
  • Inspect vinyl-roof seams, hidden-headlamp operation, climate-control functions, and power accessories.
