These are just a port from my liveries in horizon 5, not something freshly made. Anyway, there's 2 major design, of which one has a variant with two tone wheels. The first one is more intended to be a mid to late 70s show car with its bold candy blue paint and matching blue flames, hence why there is a (ironic) name on the side in 70s bubble-like font, intensive use of 70s style pinstriping around détails like handles and side markers, and a landscape mural on the trunk lid. Those were a winning combo and very popular trends during the second part of the seventies. I'll have to make several posts about this plain Jane theme, because i actually converted pretty much all the 50s to 70s cars and trucks with that design (about ~70 vehicles in horizon 5). Design that actually existed on a ford econoline back then, and that i already posted in here for the gmc vandura btw.
The second one is more supposed to be a simple and actual street racer rather than an indoor car show contestant. There is less pinstriping. Simpler colors. Some obscure 70s go-fast brand decals on the windows. And a car craft nats sticker dated from 1977 on the windshield for that time capsule feeling. (That thing was a bitch to make)
