Iv drove both and drove nxt to an altezza and ther is a masive difference in power plus the tezza is easier to tune.
Im thinking about buying altezza manual and swaping the luxuary of my is and puting it in tezza
then selling my is
but.....
then i think if i want quick buy a evo or subaru
i saw a wrx sti L reg 62k 300bhp sell for £1800
got to be honest got my eye on a 52 plate m3
