Should I check the MOT history before buying a 2003 Suzuki An400?

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.

The 2003 Suzuki AN400 is noticeably more reliable than average, with an 89.3% first-time pass rate against the UK benchmark of 80%, but nearly a quarter of tested vehicles (21.5%) have recorded dangerous defects at some point, which is a legitimate buyer concern. This is a maturing machine: at 16,243 miles on average, these scooters are showing their age but not excessively racked up, and the relatively low failure count of 1.31 per vehicle suggests most issues are minor when they do arise. The high advisory tally of 4.9 per vehicle indicates accumulated wear—worn pads, weathered trim, tired electrics—typical of a two-decade-old commuter scooter. Before committing to one, have an independent MOT inspector specifically check the brake and fuel systems, since those tend to be where the dangerous defects turn up on older small-engined bikes.
