I did manage to recreate Packard Walsh’s Corvette from the movie (look up “Packard Walsh” for the designs of the 1970 Corvette ZR-1, even tho Packard drove a '77 C3) but having the M4S would be really sweet. There’s also several other cars from the movie that could show up, perhaps as easter eggs, or as a car pack.
1986 Dodge Daytona (white car driven by George at the beginning of the film, red car driven by “Oggie”)
1966 Plymouth Barracuda (driven by “S----k”, forum censors the character’s name but y’all can look it up if you care to)
1977 Pontiac Firebird Trans Am (driven by “Minty”)
1975 Triumph Spitfire 1500 (driven by Billy)
1982 Plymouth Gran Fury (police cars)
1985 GMC C-1500 (driven by “Rughead”)
