When I was looking for a mk6 fiesta for the Mrs we traveled a fair way to view a 'mint' fiesta,
As soon as we pulled up it was clear it wasn't. Both front tyres on the limit. Lifted the bonnet and pulled the dipstick and it was almost bone dry.

Needless to say we walked away, I said to the guy 'I think your taking the piss' He just said yeah, Im sorry.
