Cambelt changes often skipped
A failed cambelt can wreck the engine, and because the job can cost close to what the car is worth, some owners skip it. Many specialists advise changing it more often than 100,000 miles or ten years, especially on diesels.
At the viewing: Check the service history for a cambelt change.
- All engines
Sill rust
The sills can corrode with age.
At the viewing: Look along and under the sills for rust.

Electrical faults, wet lights and windscreen heater
Electrical parts are prone to fail, water gets into the headlights and tail lights and blows bulbs, and the Quickclear heated windscreen elements fail.
At the viewing: Check all lights for water inside, and test the heated windscreen.
