Should I check the MOT history before buying a 2021 Audi RS 6 Crbn Blk TFSI MHEV Quat A?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

How are tyres and brakes typically on a 2021 Audi RS 6 Crbn Blk TFSI MHEV Quat A?

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.

The 2021 Audi RS 6 passes its MOT on the first attempt 84.5% of the time, which is comfortably above the UK average of 80%—a solid result for a high-performance car of this age. The 14.9% dangerous defect rate is acceptable and shouldn't be a major red flag, though it's worth getting a pre-purchase inspection on any used example.

At just over 26,000 miles median, these cars are running low mileage for three-year-old vehicles, which explains why the average failure rate sits at only 0.24 per car—owners aren't driving them hard or far. The 0.7 advisories per vehicle suggest minor wear items crop up occasionally, but nothing systemic. Before buying, insist on a full service history and have a specialist check the cooling system and turbo seals, as RS models can be expensive when they do fail.
