Tamiya has some nice 200mm touring car bodies, I dont think ther eis a German car in the mix,but you should check them out. Kyosho has some also.
You can pretty much give up on any other companies even trying to give you something wth scale.
I dont like jelly bean cars, And its strange as a i think 1/8th has more scale than modren 1/10 GP cars.
