The revolution may be cheaper than an STi used
I'd prefer the 2.5 in the subaru over the mitsu.. and subaru quality over the mitsu... but there are trade offs on either side i do believe.

If you catch them at year end, right before they release a new model you can save a ton...
For example, my legacy MSRP'd for 27,2K. Invoice was 25,2K, dealer invoice was 23,5K or so. I paid 22,5K because the 06 was about to come out which meant the dealers were clearing their lots AND subaru had a 1500 instant rebate on top of that.
