The only problem I see with the CLA estate is that it's too small for American tastes. The CTS is really equivalent to an E-class, while the CLA is two classes lower. A CLA wagon would probably be the size of those old Impreza "wagons", which are barely bigger than a GTI or Mazda3 four door hatch today. I think it'll probably do fine it the EU, especially in the UK. But I doubt it'll be doing all that well here. MB may have a better chance bringing the B-class over (which I think they are, but only in electric like the Ford C-Max). Not as nice looking, but at least it is more in tune with the girth stateside. And it wouldn't even be too hard, since they already have it in Canada. You just need to add 300 pounds of deadweight and then you can sell it in the US.
Shooting-brake, shooting brake or shooting break is a car body style that has evolved through several distinct meanings over its history.
Shooting-brake originated as an early 19th century British term for a vehicle used to carry shooting parties with their equipment and game. The term brake was initially a chassis used to break in horses — and was subsequently used to describe a motorized vehicle.
The term was later applied to custom-built wagons by high-end coachbuilders and subsequently became synonymous with station wagon or estate.
In contemporary usage, the term shooting-brake has broadened to include a range of vehicles from five-door station wagons — to three-door models combining features of a wagon and a coupé.
In 2006, The New York Times said the shooting-brake was conceived "to take gentlemen on the hunt with their firearms and dogs." and "although [its] glory days came before World War II, and it has faded from the scene in recent decades, the body style is showing signs of a renaissance as automakers seek to invent (or reinvent) new kinds of vehicles for consumers constantly on the hunt for the next new thing." In 2014, Lawrence Ulrich of the New York Times said the shooting-brake is "essentially a two-door station wagon."
Shooting brake in my mind is either a station wagon or a hatchback that took too much viagra. I think shooting brake, like estate, is mainly a UK term. I've only heard either a couple of times on this side of the pond. I don't think a shooting brake is necessarily a coupe with a big trunk. I've heard it used on five door wagons multiple times.
