Should I check the MOT history before buying a 2017 Audi S3 TFSI Quattro S 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.

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.

Do I need an HPI check when buying a 2017 Audi S3 TFSI Quattro S A?

This 2017 Audi S3 is a significant reliability concern: only 50.5% of vehicles pass first time, nearly 30 percentage points below the UK average of 80%. The good news is that dangerous defects are absent from this cohort, and failure rates remain low at 0.06 per vehicle on average.

At a median mileage of 49,098 miles for a seven-year-old car, these examples are relatively well-used but not excessively so—the low failure count suggests issues tend to be minor when they do occur. Before committing to a purchase, have a pre-buy inspection focus on the transmission and suspension systems, which are likely driving the high first-time fail rate on MOT.
