Should I check the MOT history before buying a 2015 Sym Av?

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 2015 Sym Av?

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.

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 2015 SYM AV passes its first MOT attempt 82.2% of the time, which is slightly better than the UK average of 80%, but the concerning figure here is that 25.9% of vehicles have recorded a dangerous defect at some point—well above acceptable levels and a genuine buyer red flag. This scooter/moped has a history of serious safety issues that warrant careful inspection before purchase.

With a median mileage of just 9,288 miles for a nine-year-old vehicle, these machines are lightly used, which should work in their favour—yet they still average 0.85 failures and 2.9 advisories per test, suggesting mechanical fragility rather than wear-and-tear neglect. Before committing to one, get a pre-purchase inspection done by a specialist familiar with SYM models and specifically ask the seller about any past MOT failures or defect history, as the elevated dangerous defect rate indicates design or build quality concerns you'll want to investigate yourself.

We have limited data for the 2015 Sym Av — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
