The 1998 Rover 623 is a below-average performer in MOT terms, with a first-time pass rate of 68% compared to the UK average of 80%—and one in four of these cars have recorded a dangerous defect at some point, which is a genuine safety concern for buyers. This is an older car that's now 26 years on the road, so some wear is inevitable.

At nearly 100,000 miles on average, these vehicles have covered typical mileage for their age, but the real problem is consistency: the average car has nearly 3 failures and 8.5 advisories per test, indicating that mechanical issues are the norm rather than the exception. If you're seriously considering one, budget for repairs and get a thorough pre-purchase inspection focused on the systems that fail most often—you'll want to know exactly what you're inheriting before you buy.

The 1998 Rover 623 has a below-average first-time pass rate (68% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.
🔧 Expect consumable spend. An average of 8.5 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 622 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
