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 | 14,500 | 21,800 miles | 30,400 | 30,900 |
| 6-8 years | 21,200 | 29,300 miles | 39,800 | 51,800 |
| 9-11 years | 33,800 | 48,000 miles | 65,300 | 73,500 |
| 12-14 years | 46,300 | 63,400 miles | 82,100 | 91,400 |
| 15-17 years | 55,900 | 75,400 miles | 95,900 | 101,600 |
| 18-20 years | 66,900 | 88,700 miles | 111,400 | 106,700 |
| 21+ years | 72,600 | 96,100 miles | 118,600 | 99,200 |
