$3,000 for one is cheap. If it's a 2 seater, it'll be a restoration for sure. A 2+2 you'll be able to drive it home, but will probably still need a bunch of work for a roadworthy cert.
I'm not really sure you intentions for the car, and whether $3,000 is your total budget, or just the initial budget with plans to spend more (which is inevitable)
