I'm imminently taking delivery of my new Fiesta. I've never owned a new car before. Obviously when I take delivery I have to sign something saying I've examined the car and am satisfied with condition etc.

Obviously I know the main things to look for, cosmetic condition, no scuffs or marks, properly inflated tyres, no marks on wheels or anything - but what else should I be looking for, less obvious than this?

Any tips appreciated
