If people hadn't already done so, I recommend you purchase a recent (last 12 months) Kyosho 1:18 R32 GT-R in either wine red or gun grey.
I have been getting them as they are being released, and can't say enough good things about them:
For those that aren't aware of the size difference between 1:64, 1:43 and 1:18, I have compared them here:
My group shots of a selection of Ebbro's 1:43 cars. If anyone is considering Ebbro, go for it.
My collection of diecast:
The 1991 Bathurst cars are fetching between AUS$180-220. The 1992 Bathurst winners are fetching between AUS$550-600 on ebay. Crazy money for what is quite a crude diecast (based off original c. 1991 Kyosho moulds).
N1GTR - For a 1:18 White R32 GT-R V-spec II, see here: http://www.biante.com.au/product_16530.htm
AutoArt product code A77345. You can order this car anywhere in the world with this code. I don't have pics of mine handy unfortunately, but it is very VERY well finished and will set you back in the vicinity of AUS$110-$125 RRP.
