How to use this quiz
Answer the 6 questions on age and mileage, last year's repair costs, perceived reliability, fuel efficiency, financing readiness, and lifestyle changes honestly. Each is scored 0-3, with three answers carrying particular weight: an older vehicle with high mileage, annual repairs above $2,000, and a feeling of unreliability push strongly toward replacement. Be brutally honest on the reliability question — "something always feels off" or being stranded is a safety signal, not just a financial one. On the financing question, don't answer based on hope; check your actual credit and pre-approval before you interpret the result.
What your result means
65+ means the financial and practical case for replacing is strong — repair costs and fuel inefficiency are likely costing more than a newer vehicle's monthly cost of ownership. 35-64 means mixed signals; the practical compromise is to set a decision deadline (e.g., the next repair over $500, or hitting a specific mileage milestone) rather than letting indecision drift. Below 35 means your car is in its sweet spot — depreciation has slowed, reliability is solid, and keeping it (with continued preventive maintenance) is likely the financially smarter move. The single most decisive rule embedded in the scoring: when annual repair costs approach half the car's market value, replacement usually makes financial sense — check Kelley Blue Book, Edmunds, or CarMax for actual current value.
When to trust it
This quiz gives a directional nudge, not a purchase recommendation. It can't see safety recall history (check the NHTSA vin lookup for your vehicle), crash-test ratings of either car, your actual insurance quotes for the new model, total cost of ownership including depreciation, or whether a used car you're considering has hidden damage. Before buying, get an independent pre-purchase inspection from a mechanic who works for you (not the seller), compare financing offers from a credit union and at least two lenders, and run the real numbers through a car payment calculator with current rates. For EV or hybrid decisions specifically, factor in charging installation costs and local electricity rates — they change the math considerably.
