Hi Mark,

The 07 Corsa isn't the worst in terms of reliability, but a 13-year-old car can't be expected to be as-new either, obviously.

The 1.0-litre engine has a timing chain.

A few things to watch out for:

- Make sure it's not difficult to engage gears, as it could mean a gearbox-out job to remedy.

- The dials in the instruments may appear to fluctuate and the warning lights come on randomly. That requires some fiddly wiring work behind the dashboard.

- Poor throttle response is likely to be due to an air leak somewhere, but it's known to be difficult to trace and fix.
