I REALLY want a white vehicle with black wheels, so that gets my vote. However, if I had to choose between these three specific Tundras I'd go with the grey. The whateverthatis on the grill and top of the front bumper on the white one is driving me insane. It looks like it was copy and pasted on photoshop, and I cannot stop looking at it.
White is an easy color to make look good. Grey looks great, but it's dark enough that any water spots will show, dust/dirt/grime will show. Beautiful color, however. I messed around with a girl in High School whose dad drove a blue Tundra like that one. Nope. It's also a bit flashy for me.
Promise me you won't buy a vehicle from those clowns, lol...
