Oh, the other "problem" is that it is manual transmission. Slushboxes suck up fuel economy like most people don't even believe.
Technology has moved on you know, Semi-Auto boxes, its basically a manual box with a computer controlled clutch and shift mechanism, the manufacturers claim that in full-auto mode these get BETTER fuel economy than the equivalent manual in average driving conditions, as the computer wont run the engine at higher revs/gear combos than is actually needed.
Having driven a manual all my life i find myself now just leaving this in full auto mode, its right most of the time, and when i know something it cant anticipate, like a hill coming, i just flap the appropriate paddle and it changes gear at my request and carries on. If it ticks you off (i thought it would but it never has) you can just switch to manual mode and change gear up/down yourself.
