MOT
The Ultimate MOT History Check Guide
The DVSA's public MOT database holds the testing history for every vehicle in the UK since 2005. It's a goldmine of information if you know what to look for.
1. Spotting the 'Quick Flip'
If a car has just been MOT'd after sitting idle for a year, and passed with no advisories despite failing heavily the previous year, proceed with caution. Ensure repairs were actually done to a high standard, not just temporarily patched to get a certificate.
2. The DPF and Emissions Red Flags
For diesels, keep an eye out for emissions failures. If a car repeatedly fails on emissions or has advisories for a 'noisy exhaust' or 'engine MIL (engine management light) illuminated', it could indicate a blocked DPF (Diesel Particulate Filter) or failing EGR valve—both of which are very expensive to fix.
3. Checking for Accident Damage
MOTs don't check if a car is a Category S or N write-off, but they can leave clues. If a relatively new car suddenly needs a new headlight alignment, steering rack adjustments, or has bent suspension components, it might have been in an unrecorded shunt.
