Moderate sample. 340 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 1996 Proton SL is in serious trouble on the road—just 20.3% pass first time against the UK average of 80%, which means four out of five examples are failing their MOT. The good news is that dangerous defects are rare at 1.8%, so the failures are fixable rather than catastrophic.

These cars have covered a modest 75,870 miles on average, suggesting they're genuinely aged rather than thrashed, yet they're still accumulating 0.3 failures and 0.5 advisories per test. If you're considering one, treat it as a project requiring immediate pre-purchase inspection by a trusted mechanic, because the failure rate suggests systemic wear rather than isolated problems.

The 1996 Proton Sl passes its MOT first time at roughly the UK average rate (76.6%) — solid but worth checking this vehicle's history carefully.
