Hi Nadine,
My first idea was to paint the Truck Viper red with stripes...but I didn't have the guts, so...
I decided to paint the Truck in grey metallic, in order to expose the race car(s) more. I also use the truck for the Motorbikes and the Snowmobiles, so the neutral color combination was a good choice...
...Nadine, that's for sure a good looking Avatar!
