As most people have suggested above hold out for an sti, it's going to be as quick as you need it to be if you were contemplating a wrx. And as the car market is flogged out atm you can pick up sti's similar year and km's as some wrx's. (when people get desperate)

For e.g i picked my 05 sti up for under 20k with 125000 on the dash, although the car wasnt in perfect condition its still going to be cheaper spending 4k getting it up to scratch, as a pose to buying a 20k wrx and spending 15k+ trying to make it an sti.
