lol dude no offense but you should educate yourself a little bit before putting so much trust into rumors, especially about Mitsubishi and their evo. Anyways, it is required by law for the warranty to be honored and for parts to continue to be manufactured for a few years after a model has been discontinued. Regardless, there's a ridiculous amount of aftermarket support for the evo, scarcity of parts or whatever would be highly improbable even if mitsu cut off all support immediately for whatever reason. The evo x runs 22 lbs of boost stock and will clock 100k miles no sweat with just your average fluid changes and maintenance, as far as I'm aware there should be no reason to worry. Also let's not forget that Mitsubishi motors is a subsidary of a massive well established multinational conglomerate. They're not exactly just going to disappear off the face of the earth. Mitsubishi certainly makes questionable business decisions, however if one thing is certain it's that the evo was done right.
My point is, the only reason you or anyone else shouldn't get an evo is if you or they don't like the way it drives.
Sort of off on a tangent/stirring some shit up:
I can't be the only one to notice that mitsu, aware of it or not, was way ahead of the game back in 2007 when they created the evo x, MR trim specifically: a performance turbo 4 cyl paired with a DCT. Now, what was that thing porsche was gonna do sometime in the near future?
