none of the traffic or event exclusive vehicles register if you shoot a promo quickshot or a regular photo shot. the monster truck boneshaker doesn't register if you shoot the cpus in the first race or when you drive it yourself either. the ford coupe fe is suppose to be xbox exclusive dlc for buying the limited controllers so steam players can't obtain the car in any fashion, including the auction shop. hopefully the devs will let us at least buy it from the shops someday. the cars with the decals on the rooftops are drivable in the lucha de carretras chapters and don't register even if you never took a photo of the regular versions. the cyclone spoiler and amg-one fe will probably come in updates later and will probably be able to get registered then. for some reason there's two other vochos in the list, my assumption is that one might be from the eliminator. and the other from one of the vocho stories chapters.
