Should I check the MOT history before buying a 2021 Audi Q3 S Lne Blk Ed 40 TDI Quat SA?

How are tyres and brakes typically on a 2021 Audi Q3 S Lne Blk Ed 40 TDI Quat SA?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.
