Well, Jaguar has come up with the improved version of XF Sportbrake and it seems like they're expecting some really good sales of that model. Personally, I'm not sure that current market is looking for a luxury wagon and this idea looks pretty risky to me.
BMW sort of paved the way for this with them bringing the 3-Series wagon around even though sales were slow and oddly enough Audi and Mercedes started offering wagons for the segment above the 3-Series. So already we can see there is some demand.
