The dealership I work for bought a Mitsubishi franchise. I have a little bit of seat and class time on the EVO X.
The chassis is superhuman. The electronic nannies make the car unshakable in all but the hardest, craziest driving situations. The car is deceptively fast - I thought I was puttering along, short shifting like my granny, when I looked down at the speedo I was in the triple digits in 4th gear with plenty of go-pedal left. Power delivery is buttery smooth - they say the VIII and IX are faster, but the power delivery is like a light switch, kinda dull down low then WHAM, you're moving. Not this car. The 4B11 in the X does away with timing belts, so you don't have to worry about that every 60K or however many miles.
I've been told that all Evolutions are hard on clutches, whether they're driven easy or not. As a 911 owner it probably doesn't bother you, but the ride quality is pretty brisk on broken, rough pavement.
I'd love to own one myself, so long as I didn't have to fix it when it breaks.
