The 2006 Alfa Romeo 159 passes its MOT first time in only 72.1% of cases, notably below the UK average of 80%, and nearly half of these cars (45.1%) have recorded a dangerous defect at some point—a serious red flag for potential buyers. Both diesel and petrol variants perform similarly poorly, with pass rates of 71.5% and 73.7% respectively, suggesting the reliability issues are inherent to the model rather than fuel type.

These 159s are running at a median of 90,000 miles, which is reasonable for 2006 models, yet they're averaging 4.27 failures and 18.9 advisories per test, indicating widespread mechanical wear across braking, suspension, and emissions systems. If you're considering one, budget for immediate professional inspection focusing on brake condition and exhaust integrity, and factor in ongoing maintenance costs—this is not a low-hassle used buy.

The 2006 Alfa Romeo 159 has a below-average first-time pass rate (72.1% 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 18.9 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 1,621 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.

Under-trays fitted obscuring some underside components · Oil leak, but not excessive · Engine covers fitted obscuring some components in the engine bay · …
Brake wear 40.2%
Front Brake pad(s) wearing thin · Parking brake: efficiency below requirements · Front brake disc worn, pitted or scored, but not seriously weakened
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
