When should you replace your car?

Short answer: Once a car passes 8–10 years, the factory warranty is gone and repair bills climb fast. That's the window to price a replacement or an extended warranty — before a big repair forces the call on the shop's schedule, not yours.

The math flips when a single repair approaches a big share of the car's value, or when repairs start clustering. A timing belt, a transmission, or an AC compressor back-to-back is the market telling you it's time.

Plan it and you get three quotes and your pick of timing. Wait for the breakdown and you take whatever's available at whatever it costs. An extended warranty can bridge the gap if you want to keep it a few more years.

Common questions

How many miles is too many for a car?

Modern cars routinely reach 150k–200k miles with maintenance. Mileage matters less than repair pattern — a well-kept 150k car can beat a neglected 90k one. Watch for clustering repairs, not a single odometer number.

Is it better to repair an old car or buy new?

Keep repairing while individual repairs stay well under half the car's value and don't cluster. Once they exceed that or pile up, a replacement usually wins — see the repair-vs-replace guide for the math.
