Moderate sample. 458 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 1995 Proton SL is a seriously unreliable car by any measure—just 17.9% pass first time compared to the UK average of 80%, meaning four out of five will fail their MOT. The good news is that dangerous defects are rare at 0.9%, so while these cars are old and decay-prone, they're not inherently unsafe.

At an average mileage of 78,109 for a nearly 30-year-old vehicle, these are relatively low-mileage survivors, yet they still rack up 0.33 failures and 0.7 advisories per test on average. If you're considering one, assume you'll need to budget for significant repairs before and after each MOT—these cars need an honest pre-purchase inspection by a mechanic familiar with 1990s Asian imports, because age and parts availability will be your real enemies.

The 1995 Proton Sl has a below-average first-time pass rate (73.1% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.
