Car Looks alright,
Personally i don't like the H.I.D's though I can see why you got them, extra light, especially considering my headlights (classic mini) are about as much use as a fart in a space suit. I personally don't like tints unless its an OEM Green/Blue like some manufacturers did, Rover did green on the last few mini's and mercedes benz do blue tints.
17's don't suit the car but the 15's in white should be nice, pick up some poorboys wheel sealant will protect them and will make cleaning them a lot easier! I really don't like the idea of cheap coilovers, there is a reason they're cheap, a set of lowering springs from ebiach may be a better choice.
