More Nascars + Issue

Ok so let em go out on a limb and say I’m not wanting more Next Gens, I’m meaning like the COT’s, Gen 4’s, Late Models, and the Garage 56 Le Mans car, plus I don’t know if this is an issue, but why can’t we paint the Toyota Camry Next Gen, like we can paint the Dark Horse and the Camaro but not the Camry?
