Head to head
| Kia | Mini | |
|---|---|---|
| Cars inspected | 150 | 25 |
| Average condition | 70/100 | 63/100 |
| In good shape (60+/100) | 70% | 64% |
| Repainted or replaced panel | 68% | 60% |
| Structural repair found | 1% | 0% |
| Fault codes recently cleared | 23% | 36% |
Green = the better number of the pair. Condition reflects the mix of cars that came to us — age, price, model — so treat small gaps as a tie.
How they score
How long do they stay good?
Good cars by mileage
▬ Kia▬ Mini▬ all cars
Good cars by age
▬ Kia▬ Mini▬ all cars
Share in good shape (scoring 60+/100) by mileage and by age when we inspected them (each dot ≥5 cars; a band under 20 cars follows the nearby bands, so a run above the all-cars line stays above it, and a band of 20 or more uses the rate we measured; where a band has too few cars, the line follows the trend between the bands on either side; rolled-back odometers excluded from the mileage curve). Dashed grey = all cars we check. Not enough Mini data at this granularity yet.
