Moderate sample. 443 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 1997 BMW 840 has a first-time pass rate of 76.5%, which sits 3.5 points below the UK average of 80%—a modest but real reliability disadvantage. More concerning is that nearly a quarter of these cars (23.5%) have experienced a dangerous defect at some point, suggesting buyers should prioritize a thorough pre-purchase inspection and budget for potential safety-critical repairs.

These 840s are running around 100,000 miles on average, which is reasonable for their age, but they're averaging over 4 failures per MOT and nearly 25 advisories, indicating these are higher-maintenance vehicles than typical 1990s saloons. Before committing, have a trusted BMW specialist inspect the cooling system, electrics, and suspension components—the high advisory count suggests these are recurring weak points on the model.

The 1997 BMW 840 passes its MOT first time at roughly the UK average rate (76.7%) — solid but worth checking this vehicle's history carefully.

⚠️ 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
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 24.8 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 443 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.
