Best starter cars for an enthusiast?

I'm in need of a new car soon, as the hand-me-down 2001 Forester is on its last limbs of life. I need a manual car, preferably turbo and AWD, but will consider RWD. I absolutely will not get anything FWD, especially a Honda. Budget is $5,000 and don't want to be spending too much on insurance. Any suggestions? I wanted a WRX, but they're overpriced because I'm in a snowy state.

Subaru Impreza
Mazda 3
Mazda 6
Mazda RX-8
Mazda MX-5

Or you can get a 96 - 2001 impreza and build your own WRX.
Otherwise hold out and save a little more. 02-03 bugeye WRX can be found for under $10k.
