I think the '68 Mustang, because MM2 has SF,so you could be like Steve McQueen from "Bullit". And yes, it's spelled that way.
Oh, and the London Cab or the Mini Cooper for London.
PS: They must have planning SF from the start, like how the code name for the 68 Mustang was "vpbullit",and it had a California plate, and how the fuel cap on the back said "GT", and it had no fog lights in the grill, which the REAL Bullit Mustang had.
