Should you buy a used Proton GEN-2?

The Proton GEN-2 has an overall MOT pass rate of 70.5% across 59,272 real MOT tests — roughly in line with the UK average.

The most common problems on the Proton GEN-2 are tyre tread depth below requirements of 1.6mm (2,238 recorded failures), parking brake: efficiency below requirements (2,173), and parking brake recording little or no effort (1,549). 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. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.

A typical Proton GEN-2 owner drives around 5,392 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.

In terms of longevity, most Proton GEN-2 models stay on UK roads for around 22 years — a strong showing that suggests solid build quality and readily available parts. 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.
