UK & US differences
From what i've gathered you guys across the pond have one standard power level but then have an option of different trim levels.
It works a little differently over in the UK.
We just have one trim level but then have different power levels 300bhp, 320bhp, 340bhp, 360bhp and the 366bhp MR version.
Of course your evo can be tuned after purchase but i still find it odd that mitsubishi sell the evo in the US with significantly less power.
