Looks pretty solid. Places to check are the inner fender wells around the engine. They rust out and they don't make replacements for them. Also check the frame rails in front where the lower cross brace bolts in.
They do make floors for them now and rear quarter skins too if needed.
I think the 2750 is a bit high, but not by much. These are fun little cars, the only down side to them is so many rarer parts or parts for these cars only and there isn't much in the way of repop parts for them.
There's more activity and a ton of info there on these cars and how to's on some cool mods.
So get some more info/pics. If it's solid, I'd say go for it.
