Great choice, personally I think there is not one colour that looks bad on this car.There were 2 fully loaded GS near me (London ON) last week, one black, one white tri-coat. Since my last two cars have been black I really needed a change, and ended up getting a fantastic deal on the white. TBH you really can't see anything special about the tri-coat until you're up close, but in general I think white complements the car's shape nicely.
I have had problem with white cars since buying my 70 TA, although bought Typhoon in Royal Blue Metallic since only few made at very end of production run. I could not get Sierra Denali in white with Quadrasteer.
