Hi, you can get a decent early 944 for the sort of money you are talking about, I know because I've just got one !
You need to be prepared to look at several before buying to give yourself an idea of whats good and whats not. I looked at several (previously rusty) examples that had recent paint and looked ok, but I am always wary of anything recently sprayed, as in my experience, in the price range we are talking about, they've just been tarted up to sell and the rust soon returns.
Mine had badly faded red paint and looked a bit rough, but it was fundamentally sound and has no rot. It has now been T cut and polished and has come up really good.
Mechanically, check for engine noises, gearbox whine etc, look for blue smoke and check oil pressure with the engine hot. Try and get one with a recent clutch as this is one of the hardest DIY jobs.
If you get one be prepared to do things like electrics, brakes, wheel bearings, and cv joints yourself, and you can keep the running costs down. My 944 is a second car and a hobby, I actually enjoy doing jobs on it !
Good luck with your search.
