How do I know if my car is worth repairing?

Compare the repair cost to your car's current market value. If the repair costs more than 50% of the car's value, it's generally not worth fixing — especially on high-mileage vehicles. Use DriveOrDitch to get an instant AI-powered verdict based on your specific car and symptoms.

What is the 50% rule for car repairs?

The 50% rule says: if a repair costs more than 50% of your car's current market value, you're better off selling or replacing it. For example, a $1,500 repair on a car worth $3,000 passes the test. A $2,000 repair on the same car does not.

Is it worth fixing a car with high mileage?

It depends on the repair, the car's reliability history, and its remaining value. A timing belt on a well-maintained Honda at 150k miles may be worth it. An engine replacement on a 200k-mile vehicle with multiple failing systems usually is not. The key is repair cost vs. what the car is actually worth today.

When should you stop putting money into an old car?

Stop investing in an old car when: repairs exceed the car's trade-in value, multiple major systems are failing at once, or you've spent more than the car's value in repairs over the past 12 months. One expensive repair is often fine; a pattern of expensive repairs signals it's time to move on.

Should I fix my car before selling or trading it in?

Usually no. Dealers expect wear and price accordingly — you rarely recoup repair costs dollar-for-dollar in trade-in value. The exception is cheap cosmetic fixes (under $200) that dramatically improve curb appeal. For mechanical repairs over $500, sell or trade as-is and let the buyer factor it in.

Here's what you'll get — in 60 seconds

No guesswork, no vague advice. Just a clear verdict backed by repair estimates and market data.

2016 Honda Civic LX, 147,000 mi

AC blows warm, rattling noise at startup, check engine light on

EXAMPLE

Repair Estimate

$800 – $1,200

Vehicle Value

$8,500 – $10,200

Repair/Value Ratio

9.5%

Fix It ✓

Repair is 9.5% of vehicle value — well within the 50% threshold. Worth fixing.

Why this verdict

AC compressor failure is a common Honda issue at this mileage — typical repair costs $800–$1,200, well within range for a 147k-mile Civic.

Trade-in value of $8,500–$10,200 means the repair costs less than 15% of what you'd get selling the car as-is.

Civic reliability at this mileage is above average — no major red flags on compression or transmission from the symptom description.
