If I was buying a car for track days, and you're looking at that kind of budget, I wouldn't be buying either to be honest. I'd be looking at Elises, Caterhams etc etc.
However, I think what you should do is try and drive an Evo and see what you think of it. That's the only way you will really know. I think Pete's advice is wise too, go for an RS model if you can, as it will feel more raw and "special" which will make it more of an experience to drive.
