Wagons are generally considered not viable in the U.S. Just about every recent wagon model has failed, though there are exceptions, usually for crossovers that straddle the line between wagon and wagon-like (Subaru, looking in your direction).
Even the Jaguar XF Sportbrake, which this author found quite sexy, was sent packing.
All that said, Mercedes-Benz might be trying to bring a wagon back to our market
The company offers a C-Class wagon elsewhere, but Americans can’t get it. Now, however, spy shots show that the C-Class All-Terrain could be coming to America.
The All-Terrain straddles the line between crossover and wagon — it’s basically a raised version of the latter — and it would likely target Audi’s A4 AllRoad and the Volvo V60 Cross Country.
If it comes to America, that is. Autoblog makes clear there is no hard evidence that M-B has America as part of the sales plan, but it’s not unreasonable to think that Mercedes could bring the All-Terrain to our crossover-crazed shores to siphon some buyers from the aforementioned competition. The luxury wagon/crossover segment is niche, but the sales still count.
