Used buying checklist
Audi Q8 reliability, common problems and used buying checks
A used Audi Q8 looks better than average for reliability in UK MOT data: 7.5% of 3,033 tests failed, compared with 18.7% across all indexed models. A good example should have a clean MOT history for tyres and wheels, windscreen, wipers, and mirrors, and lights and electrical.
It can be, if the exact car has a clean history for tyres and wheels, windscreen, wipers, and mirrors, and lights and electrical.
