The 1997 Rover 620 is well below the UK average, with only 65.8% passing MOT first time against the national 80% benchmark—and one in five of these cars have recorded dangerous defects, which is a genuine buyer concern. Petrol versions fare marginally better at 66.5% pass rate, while diesels slip to 64%, suggesting neither powertrain offers a reliability advantage.
These 620s are averaging 110,700 miles, which is reasonable for 27-year-old cars, but they're racking up 2.47 failures and 6.3 advisories per test, pointing to accumulating wear across multiple systems rather than one specific weak point. If you're seriously considering one, budget for repairs before and after purchase, and treat the MOT history as your roadmap—a car that's passed consistently is far more trustworthy than one that scraped through with multiple attempts.
The 1997 Rover 620 has a below-average first-time pass rate (65.9% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.
