i assume you're looking at buying the 65 fastback? seems like a reasonable deal. ensure that the car has ZERO rust. ask for undercarriage (footwell) photos as well as photos of the front lower doors.
also ensure the car is a FACTORY GT. ask for photos of the rear frame-rails where the exhaust attaches, the floor area under the rear seat, and photos of the disk brakes.
hope this helps.

ps if you want a great factory GT (convertible) i'll be selling a bare-metal restored springtime yellow/black pony, 4-speed, A-code, heavily optioned car in about a month.
