Typical mileage
Recorded mileage at the MOT. A car well above the range for its age has done more work than most; one far below is worth a closer look at its MOT history.
| Age | Low | Typical | High | All cars, typical |
|---|---|---|---|---|
| 3-5 years | 9,500 | 15,500 miles | 23,900 | 30,900 |
| 6-8 years | 18,300 | 27,100 miles | 37,300 | 51,800 |
| 9-11 years | 24,600 | 36,000 miles | 50,400 | 73,500 |
| 12-14 years | 33,400 | 47,100 miles | 62,900 | 91,400 |
| 15-17 years | 43,600 | 60,900 miles | 79,100 | 101,600 |
| 18-20 years | 55,000 | 73,900 miles | 94,700 | 106,700 |
