The 2020 Peugeot 308 petrol models are genuinely reliable, with a 90.1% first-time pass rate that sits well above the UK average, but diesel versions tell a completely different story at just 63.9%—a 26-point gap that makes fuel choice critical if you're considering this car. Only 11.4% of vehicles have ever recorded a dangerous defect, so structural safety issues aren't a widespread concern here.

At a median mileage of 26,457 miles for a four-year-old car, these are fairly lightly used examples, which partly explains the solid petrol reliability. The average 2.6 advisories per vehicle suggests minor maintenance creep rather than serious mechanical problems, so budget for routine upkeep but don't expect major surprises—if you're looking at one, verify the fuel type first and strongly favour the petrol variants.

The 2020 Peugeot 308 passes its MOT first time more often than most UK vehicles (90.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 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
Good baseline reliability. A 90.3% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 2.6 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 3,491 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.
