I understand us gearheads being excited about stuff like the Evo (and STI, ZR1, GT-R, etc), but to the manufacturers these are 'image' cars that either lose money, or make very little.
Mass-market vehicles are what keeps a company afloat, and Mitsu has been sinking in that department for a long time now. Their stuff was barely competitive enough to be in the rental market, and I never thought I'd say this, but even Dodge cars are better than DSMs now for that use, so I think they're probably about to end US distribution entirely. They also don't have bikes to fall back on, like Suzuki does.
