Should I check the MOT history before buying a 2004 BMW 545?

Moderate sample. 365 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2004 BMW 545 falls slightly below the UK average with a 77.8% first-time pass rate, and a significant 40.8% of vehicles have recorded dangerous defects at some point—a real concern for buyers considering older luxury saloons. This model demands careful pre-purchase inspection.

At around 83,000 miles median, these cars show typical mileage for their age, but the average 4.1 failures and 21.9 advisories per test reveal why the pass rate lags: electrical, suspension and cooling system issues are common on ageing German engineering. Have any prospective purchase thoroughly inspected by a BMW-specialist mechanic before committing, and budget for non-trivial repairs.

The 2004 BMW 545 has a decent first-time pass rate (77.8%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ 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 21.9 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 365 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.
