EIDiablo Viper,
You will need to paint them yourself.
Chris,
Love your little cars; Here is what I do with 5 of mine. I have them mounted on a board that fits into the slots on the sport bar, and I display them at car shows --
the kids love them. You think Black/Silver is hard to find,......, I took apart, painted, stripped, etc. most all of these to match my car.
By the way, my small one is 1/144 scale (I see you don't have this size). It was a Blue/White GTS. I took it all apart, cut out the top section, painted it, put the windshield back in, reshaped the rear post slopes to match RT/10, put it back together, striped it, .......... about a week later,............
You might be able to find this 1/144 scale; it is on a key chain, manufactured by "Route 66" toys. I found them at KMart (I guess some still exist). Back of card says: Made for Kmart Corporation.
Chris, I also see you do not have the 1/12 scale .... that is my next one, I know where there is a RT/10 White/Blue !!
