Should I check the MOT history before buying a 1981 Audi Quattro?

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.

What corrosion should I look for when inspecting a 1981 Audi Quattro?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 1981 Audi Quattro?

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 1981 Audi Quattro hits the UK average almost exactly at 79.5% first-time pass rate—bang in line with what you'd expect for a car of this age—and dangerous defects are vanishingly rare at just 0.9%. These are genuinely solid figures for a 40+ year-old classic, suggesting the surviving examples are reasonably well-maintained.

At 86,700 miles median, these cars have covered sensible distances for their age, and the low failure rate of 0.19 per vehicle tells you that when they do fail, it's typically minor stuff rather than structural problems. If you're serious about buying one, get a pre-purchase inspection focused on rust and fuel system integrity, since those are the real enemies of early Audis rather than catastrophic mechanical failure.
