Should I Keep a Car With 150,000 Miles?

At 150,000 miles, a car's value is low and its history matters more than ever. Plenty keep going reliably; others start generating steady repair bills.

The short answer

Often yes, if it's been maintained, the model has a good long-term record and repairs are predictable. At this mileage, the car's low value means you lose little to depreciation by keeping it — so replacement usually only wins when repairs become frequent, costly or disruptive.

Why the math often favors keeping

Depreciation — usually the biggest cost of owning a newer car — is small in dollar terms on a high-mileage car. That gives you a lot of room for repairs before replacing becomes cheaper.

What to check

  • Maintenance records: oil changes, transmission fluid, coolant.
  • Signs of trouble: leaks, warning lights, rough shifting, overheating.
  • Rust, especially on the frame and brake lines in snowy regions.
  • A pre-emptive inspection from an independent mechanic.

A hypothetical example

Common mistakes

  • Assuming a specific mileage means the car must be replaced.
  • Ignoring warning signs because "it's old anyway."
  • Buying a replacement in a hurry after a breakdown, without comparing options.

When replacing makes sense

  • Multiple major systems need work at once.
  • Breakdowns are affecting work or safety.
  • Rust or structural issues make repairs impractical.
