Im looking at a Fiesta 1.25 R reg at lunch time today, just wondering what to look for on them? is there any rust points to look for? and common issues that will Fail MOT`s etc? Its Moted till Dec, and Taxed till June, and 72k miles its up for £350. I know this is cheap, so just a bit warry just in case. It has a few cosmetic problems, couple of knocks etc. but want to know what to look out for.

Cheers
