Should I check the MOT history before buying a 2008 BMW 123?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

The 2008 BMW 123 diesel passes its MOT at 80.7%, which matches the UK average—a solid result—but nearly half of these cars have picked up a dangerous defect at some point, making this a buyer concern worth investigating before purchase. With an average of 3.2 failures per vehicle and 21.4 advisories, owners should expect regular maintenance bills beyond the basics.

At 85,000 miles median mileage for a 16-year-old car, these diesels have been run hard, which explains the high advisory count and suggests you're buying into a vehicle with plenty of past wear. Before committing, get a full pre-purchase inspection focusing on the cooling system, suspension, and emissions gear—the typical weak points on high-mileage diesel BMWs of this era.

The 2008 BMW 123 has a decent first-time pass rate (80.7%), 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 21.4 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 2,043 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.
