Repair, sell, or change car: how to compare options
Compare repairing and keeping, repairing before selling, or replacing your car with a sheet to organize your options, available data, and items you still need to confirm.
Key points
There is no sufficient admissible data to establish a rule determining whether to repair or replace a car. This guide helps organize scenarios, available figures, and pending data without presenting a conclusion as definitive.
Clarify which decision you are evaluating
The question 'repair or change car?' can refer to different situations: repairing to continue using the car, repairing it to sell it, or replacing it with another vehicle. Before gathering information, write down which option you want to evaluate and which car you would have at the end of each scenario.
| Scenario | Option you are evaluating | What you need to clarify |
|---|---|---|
| Repair and keep | Continue using the repaired car | The period and items you will compare |
| Repair before selling | Sell the car after repairing it | The car valuations in each state and the quote |
| Replace the car | Switch to another vehicle | Which alternative vehicle you will consider |
Organize the data to compare
The available admissible evidence does not allow establishing a validated rule to decide between repairing and keeping or replacing. Therefore, record the data for each option without turning them into an automatic conclusion: indicate the period you want to compare, what items each amount includes, and what information is still pending.
If you have a quote or a valuation, separately note its items and the state of the car to which each figure corresponds. This will allow you to review what you are comparing without mixing data from different scenarios.
| Data or item | Repair and keep | Replace | Status or note |
|---|---|---|---|
| Period to compare | Note | Note the same period | Confirmed or pending |
| Known amounts | Note available items | Note available items | Indicate what each figure includes |
| Value of your current car | Note if included | Note if included | Indicate which state it corresponds to |
| Cost of alternative vehicle | — | Note | Indicate the vehicle considered |
| Other data you decide to include | Note | Note | Indicate if confirmed or pending |
- What period do you want to take into account?
- What specific alternative vehicle would you consider?
- Have you noted what items each amount includes and which are still pending?
Review which data can change the comparison
Before interpreting the result, check that each quote or valuation corresponds to the scenario you noted and that its items match those in the sheet. If a pending data point can modify the comparison, seek or request that information; if you cannot confirm it, leave the result as provisional.
- Check that each figure corresponds to the indicated scenario and period.
- Review if you have counted any item twice or left out one you wanted to compare.
- Note what new information you have added and which scenario it affects.
If you are selling, record valuations separately
Separately note the valuation of the car in its current state and the valuation of the repaired car, if you have both. Indicate which state each figure corresponds to, what the quote includes, and whether each data point is confirmed or pending. The information available here does not allow turning those figures into a conclusive recommendation on whether to repair before selling.
Next to each figure, note the date of the valuation or quote.
| Data | What to note | What to check |
|---|---|---|
| Valuation of current car | Available figure for the unrepaired car | That it refers to its current state |
| Valuation of repaired car | Available figure for the repaired car | That it refers to the repaired state |
| Repair quote | Available figure and indicated items | What it includes and if it is confirmed |
How do I compare repairing the car with replacing it if I am still missing data?
Identify which figure is missing and which scenario it affects. Seek or request that data before closing the comparison; if it remains unavailable, leave the result as provisional.
Does the sheet establish a percentage to decide when to change cars?
No. The available admissible evidence does not provide a universal percentage, so the sheet does not set a threshold to decide between repairing and replacing.
