Love the colour on the Bingo 432, go for it I say. But really, any original Datsun colour is just as good. As for a 432 replica, unless you have a s20 motor IMO i don't think it would be a good idea to put the 432 badges on it, especially if you are retaining the 260z tailights. Admittedly, for me I have double standards for this sort of thing. Eg, I don't mind seeing a L-powered Hako or Kenmeri with GTR badges (I'd be happy just to see one in the flesh!) but I cringe when I see GTR badges on a R32/33/34 fake GTR's. Also don't mind "replica" GT falcons, GTS Monaro's and GTR/SS/SLR Torana's.
@Gav, I do have a soft spot for the XA falcons but that gold one you posted doesn't look period to me at all. The interior colour and looks to be 17" wheels detract IMO.
Even on my zed I kinda regret going for 16 inch wheels instead of 15". My 2c.
