SOA will void your warranty in a heartbeat. They are better than Isuzu of America, but they will still laugh you off if they even think that you've been monkeying with their car. Whenever I swung by the stealership to buy oil filters/ washers, the service guys would joke about my "warranty". I guess that the gigantic FMIC tipped them off.

I found it irritating that SoA would supply you with a 1 year membership to the SCCA, but dishonor your warranty if you ever used your car to race (even against the clock).

I was actually sitting in an Evo when I decided to purchase the WRX. The things that stood against the Evo were:
1.) cable shift linkage -my bro's Civic has that, why would I want my pseudo-rally car to have it?
2.) crankwalk. The design of the 4G63 encourages it, and there's no way around it. I've seen a few 600+hp Evos and they all had one thing in common: a spare motor nearby. Maybe that's asking a lot to ask, but it's still a problem.
3.) boost gauge -right next to my shiftin' hand. WTH? Line of sight (without the cop-magnet A-pillar mounts) please.
4.) it just looks too ricey.

It did handle like a dream, but then again, I'm kind've a crappy driver, so I don't need all of that ability.
