Big repair bills force a tough question: is it worth fixing my old car? Here’s a simple way to decide.
The 50% Rule of Thumb
If the repair would cost more than about half of what the car is worth after it’s fixed, selling it as-is is often the smarter move, especially for older, high-mileage cars.
Common Repairs That Push Owners to Sell
- Cracked engine block: often means replacing the engine.
- Blown head gasket: expensive labor and a risk of further damage.
- Bad transmission: rebuilds and replacements are costly.
- Major rust or frame damage.
Texas Inspection and Repair Requirements
Texas ended annual safety inspections for most non-commercial vehicles starting in 2025, but emissions testing is still required in several counties, including Dallas and Tarrant counties. A car that can’t pass emissions in those counties can be hard to register, which is another reason owners choose to sell.
Selling a Car That Needs Major Work
Garland drivers and owners across DFW sell cars with major problems every day. A buyer who purchases non-running cars will make an offer based on the parts and materials, and tow it free.
See non-running car buying or our Garland page.
Inspection rules change. Check the Texas DPS and TxDMV websites for current requirements in your county.
A Simple Repair-or-Sell Worksheet
- Look up what the car is worth in good, running condition.
- Get a written repair estimate.
- Add any other repairs coming soon, such as tires, brakes or the timing belt.
- If the total is more than about half of the car’s value, selling is usually the smarter choice.
Hidden Costs of Keeping an Old Car
Insurance, registration, emissions testing and frequent breakdowns add up. A car that needs a major repair now often needs another one soon. Selling it can free up money for a more reliable vehicle.
When Repairing Makes Sense
If the car is otherwise in great shape, has low mileage and the repair is a one-time fix, repairing can be worth it. Get a second opinion on major repairs before you decide.
