Should I check the MOT history before buying a 2017 Audi A3 S Line TDI?

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.
