Tamiya boxed a 190 in 1/48 scale as Priller's mount, including a figure and the car. I don't know if they sold the car separately; they did for some of their other 1/48 cars that were packaged with some of their aircraft kits. There was a Citroen sedan, and a Chevy, I think, or maybe a Ford-it was a 4-door sedan-as a USAAF staff car.
Prost!
