The most common problems on the Vespa (douglas) Px are stop lamp does not illuminate immediately a brake applies (21 recorded failures), direction indicators not working (19), and wheel bearings are excessively rough (14). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection.

If you're buying one that's already approaching that window, the data suggests it has plenty of life left provided it's been maintained.

Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
