Hi All, went to look at a cougar this evening. 100k, manual, 1 years MOT and a very good and comprehensive service history. Some bubbling of paint at left rear arch and some surface rust in the arches. Took it for a test drive, getting into third was slightly awkward but engine management light stayed on. Owner says it come on sometimes but goes off. He is looking 795 for it. Should I go for it or walkaway?
