To make things worse, the Mercedes CLS will also be presented in a shooting brake version, (as a four-door car) This nothing else than a normal break with less interior space, which has been offered to present the car as a so-called lifestyle break whereby the rear section is not designed funtionally but esthetically.
I think Fiat was one of the firsts to do this with the 1500 break from the mid sixties, where the rear window was put at a 45 degree angle in stead of nearly vertical.
Anyway a four door coupe is only interesting if it also has a fully opening rear section, (something the big Citroens always lacked,) so Mercedes is getting closer to something more funtional. and yet it will always be a compromise. And for me personally, in my own choice of cars, funtion comes before shape, hence I don't like the new C5 being far too much of a life style combi and less utilitarian. It weighs 100 kg more and has 100 liter less luggage space.
