Well after wrecking my 240 I was car searching and my final choices were my nx and a mr2 n/a. the mr2 was sweet as hell cornering and whatnot but there is literally NO room in the sob. Although Im sure you could care less about that, it handled good as hell and feels really nice. the n/a was quite noticably different than the nx but im sure the turbo's quick. I wouldnt do it but its all you.
I have an older MR2 n/a and it is pretty sweet. They have a better feel than the new ones, but the new ones are way cooler looking. It handles like no other. I love my NX, but its nice to have something with mid-engine/rear drive to tool around in. I love fishtailing around corners in it. Mine only has a KN air filter, Performance exhaust,A/C removal for mods and she is pretty quick.
