Imo, any colour of an R34 GT-R looks hot. Even the most boring colour of silver looks incredibly stunning with a nice set of rims and a bit lowered. White is also boring as batshit but that Mines replica car looks so damn sexy. Red is a love / hate colour i reckon as well, but when I saw a GT-R in that colour, it made me drool because it's so damn rare to find one. And if you match a red R34 with TE37 Time Attack rims (black with red lip), I gotta say it's the best colour combination in the world.
Purple is a colour I would never ever EVER pick for a car. Furthermore, my thoughts of a cameleon coloured car would make me vomit when i see them on the road. But why do I own a Midnight Purple III coloured car? Because it looks incredibly unique on a GT-R, especially when less than 200 were made from factory (thanks for the trivia Dave, my fellow MPIII owner )
Finally, black is such a difficult colour to keep clean, even when it's slightly dirty, you can see it a mile away. But when it's kept in an impeccable condition like Bakes car, coupled with some nice dished gold GT-C's, it's a sure show winner. Bakes got my vote as well. Good work mate.
Another worthy mention was the black GT-R with Z tune bonnet and gold LMGT4's. Black matched with bronze is a sure crowd winner as well.
