Hey mate,
nice looking 2 seater. 260Z 2-seaters are my favorite given their rarity and the "big block" L26 . I agree with the others, keep all the mods bolt-on and reversible, this is what I also intend to do.
As for the color choice, is yours 240 green metallic or 303 emerald green? Sticker was on top of the radiator support panel. Looks to me like it was the emerald green. My vote would be to re-spray it the original green, the emerald green especially is a stunning color and I have not seen many others this color in Australia. Just adds that extra touch of originality, and aside from that, both of these greens are very nice colors and rare on zeds.
I think the green would also look good with the yellow iron cross wheels on it, green and yellow theme would be cool, but that's just me
Look forward to seeing the resprayed car.
