I'm not really a fan of the new hatchback they threw in for the STI....... and I certainly didn't like the 06/07 models because they borrowed that ugly ass nose from the B9 Tribeca..... all I could think was WTF? Front on the STI is looking a little better........ tail end? Meh....... I don't even like the rear end on the Evo X...... and that SHOULD look good.....ya know........cause that's all someone's gonna see when you modify it to pwn everything on the road. LOL
oh and the Evo X and the STI hatch ran near identical times in the 1/4 when a magazine tested them back to back (forgot which mag it was)
but hey man if your wife/gf gave you the green light to get it......and you can afford it? By all means........trade in the MS3...... but don't forget to check out the insurance rates for the STI as well......... may cost a big significant difference more that you might not be ok with paying.
