Frequently Asked Questions

When should I repair my car vs buy a new one?

A common guideline is the 50% rule: if the repair cost exceeds 50% of your car's current value, consider replacing. However, factors like mileage, age, reliability history, and your financial situation all play a role. Our calculator weighs all these factors.

What is the 50% rule for car repairs?

The 50% rule states that if a repair costs more than 50% of your vehicle's current market value, you should consider replacing the car. This is because major repairs on high-mileage vehicles often lead to additional repairs shortly after.

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

Generally, keeping a well-maintained older car is cheaper than buying new, even with occasional repairs. New cars have higher insurance, registration, and significant depreciation in the first few years. However, if repairs become frequent or a single repair exceeds the car's value, replacement becomes more economical.

How do I find my car's current value?

Use free online valuation tools like Kelley Blue Book (KBB), Edmunds, or NADA Guides. Enter your vehicle's year, make, model, mileage, and condition to get an accurate private party or trade-in value.
