Peugeot 307 years to avoid — 87,193 MOT tests ranked

No clear negative outlier after correcting for age. Strongest in the data: 2006 or 2008. The ranking uses 87,193 MOT tests across 7 registration years (2023–2025) and compares each year with all UK cars of the same age. Fuel-type signal: diesels show an average 3.2-point pass-rate deficit on this model. That may reflect mileage and use as well as the car itself, so inspect DPF and emissions history rather than treating fuel type as a verdict.

Every 307 year, ranked

The age-adjusted MOT index sets 100 as the pass rate of all UK cars registered in the same year and tested in the same calendar year. Higher is better. This prevents an old car being labelled a “bad year” simply because it is old.

Rank	Year	Index	Vs same-age	Pass rate	Tests
1	2008 Strong	95.1	-4.9 pts	60.2%	5,675

How to use this before buying

Rankings describe the cohort, not the car. A cherished older example beats a neglected 2006 one — always run the specific reg through the free MOT history check.
Read the advisories. Repeated notes for the same component across years mean the owner has been ignoring it. Decode them in our advisory library.
Fuel matters on this model. The diesel deficit (3.2 points) usually traces to DPF and emissions kit on low-mileage use — check for P2463-type soot codes on the test drive.
Scan before you pay. A 2-minute OBD scan reveals stored faults the dashboard hides — see our scanner guide.

FAQs

Which 307 years should I avoid?

No year is a clear negative outlier after correcting for age, so buy on condition and history rather than year.

What is the best 307 year to buy used?

2006 and 2008 lead the age-adjusted MOT ranking. The score compares each registration year with all UK cars of the same age; the specific car's history and condition still take priority.

Is the 307 reliable overall?

Across 87,193 tests, the median age-adjusted index is 92.8 (100 equals the pass rate of all cars registered in the same year). Use the spread between years as one signal, then check the individual registration.

Methodology: index = 100 + the model-year cohort’s MOT pass-rate difference versus all UK vehicles registered in the same year and tested in the same calendar year. Class 4 initial tests only; retests excluded; at least 1,500 tests per page. “Inspect” years are below both the same-age baseline and the model’s median index by at least 2 points.
