I don't think anyone would be willing to make a car with such a curved shape, seems like a nightmare to Jbeam this
I mean if you check the crap mods from modland (GTA versions) i really don't like the way they drive.
idk last time i tried that i got emailed a file and when i opened it my printer printed a page, fully black both sides just wait for it to come naturally....
Don't expect it to be done in a few days, even if someone started it right now (which is very unlikely) it would take months to be done.
