What goes wrong?
The most common MOT failure reasons are the strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, a lamp missing and inoperative or in the case of a multiple light source more than 1/2 not functioning. The top issue, the strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, caused 98 failures in 2024.

Buying a used 308 D?
Start with the free tools. Look up the specific vehicle's MOT history on GOV.UK The mileage at each test will show if it's been wound back, and the advisory history tells you what's wearing. Cross-reference that against the typical failures above to see if anything looks unusual for this model.
The free data won't tell you about outstanding finance, theft markers, or write-off history. For that, you need a vehicle history check This is especially important on a private sale where you have fewer legal protections.
With a 62.2% pass rate and an average repair bill of £162 when things go wrong, budget accordingly. 27.9% of failures on this model could actually strand you, so breakdown cover may be worth considering.
