Should I check the MOT history before buying a 2004 Daihatsu Sirion?

Moderate sample. 456 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2004 Daihatsu Sirion falls just short of the UK average with a 78.6% first-time pass rate, and a concerning 27.2% of these vehicles have recorded dangerous defects during their MOT history—a red flag for any prospective buyer. This suggests structural, braking, or steering issues are more common than you'd want in a nearly 20-year-old city car.

At an average mileage of 50,390 miles for a vehicle this age, these Sirions have been used moderately, yet they're still racking up an average of 3.64 failures and 16 advisories per test, indicating persistent wear and cumulative maintenance needs. Before committing to one, run a full pre-purchase inspection focused on suspension, brakes, and bodywork integrity, and factor in regular servicing costs—this model won't coast through ownership on low mileage alone.

The 2004 Daihatsu Sirion has a decent first-time pass rate (78.6%), 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 16 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 456 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.
