Buy an 05 Sti, you can get them for around 20-24 pending condition. Personally I repeat personally my favourite shape, comes with all the updates from the 2006/2007 Sti while retaining the EJ207.

If you want to spend 8k on modding a wrx for roughly the same price as an Sti buy the peanut drop 8k on that and win. You'll more then likely have a nice around 260whp, some nice rims and coilovers and a car I find very easy to live with.

Buy a wrx for looks and to keep it stock, if you want to mod start ahead of the curve.
