Expensive!
Not good on fuel, at all. Insurance will be a lot. Parts will be a lot. THey are quite reliable though. Gearbox is a weak spot, first gear on the EVO's and third for the 8/16 valve models. Evo's dont rust though. You need to spend as much on one as you can really, and still expect some bills. It WILL be worth it though, one hell of a car.
