High-mileage inspection plan

What to check before you keep, repair, or sell

At 100,000 miles, the odometer alone is not a sell signal. Base the decision on inspection results, maintenance history, current value, and the combined cost of the quoted repair plus the next 12 months of known work.

Inspection checklist

  • Scan all modules and keep the codes and readiness-monitor report before anything is cleared.
  • Inspect fluid condition and leaks, cooling-system pressure, charging system, tires, brakes, suspension play, and corrosion.
  • Review maintenance records and list every due item for the next 12 months, not just today's repair.
  • Get a condition-adjusted value using the actual trim, mileage, title status, body condition, and local market.

Decision signals

  • The page's condition-adjusted screening value is about $22,400; replace it with a real offer or local comparable before making the final call.
  • This mileage is below half of the model's estimated lifespan, so condition and diagnosis usually matter more than mileage alone.
  • Compare total keep cost with replacement switching cost, including taxes, registration, financing, inspection, and immediate maintenance on the replacement.
