If you want to be able to get a turbo car with 4 doors, cheap, plenty of mods that will go very fast in a straight line, get a xr6tubbo and work it.
if you want to go round corners in a light(ish) car, get an evo wrx.
if you want a car that is fast, 4 doors, pretty well build, very comfy and still handles, you need to look at mps6 / liberty gt's.
All cars can be made to have more power with the right pockets, you need to consider how much you really want. I wanted something comfortable and yet fast, that i could get some more power of (but not going for insane dyno queen power), and i knew that boost gets you laid.
I found the mps nicer to drive than the liberties, the turn in was nicer etc, but the liberty with a zorst sounds better.
The mps did have an advantage in i did a lot of reading, the libs really need the 2.5L motor, for one of them (in tuned by sti spec) you are looking at 15 grand more than what i paid for the mps. even a lib gt spec b is another 10. Bang for buck, and for what i wanted, the mps is hard to beat.
All of the above is in my very humble opinion, but i really do enjoy driving and having my MPS6
