The 1995 Proton SL Auto is a reliability concern: only 21% pass their MOT first time, compared to the UK average of 80%, meaning four out of five of these cars fail on their first test. The dangerous defect rate is mercifully low at 2.8%, so safety isn't the primary worry here—it's the sheer volume of smaller issues that need fixing.

With a median mileage of 58,542 miles for a nearly 30-year-old car, these vehicles are surprisingly well-preserved, yet they're still racking up an average of 0.44 failures and 1.0 advisories per test. If you're considering one, budget generously for repairs and have a trusted mechanic inspect it thoroughly before purchase, as the numbers suggest you'll be dealing with persistent minor defects rather than catastrophic failures.
