Well, noting what MT has done in the past, and the diminishing influence the magazine has in the publication world, I'd expect that 3 things will happen as a result.
1) There will be an up-tick in self-ego stroking posts, mostly on vortex but some here, on how wonderful we are for having purchased a car from such a wonderful german engineered
car maker.
2) There will be a substantial increase in the number of VW ads in MT, along with a remarkable number of references to the car of the year award in VW ads placed in other media.
3) There will be a barely noticeable (i.e. not statistically significant) up-tick in new car sales for VW tied directly to MT's designation. Any sales increases that are significant will be more directly attributable to deals and discounts offered by VW, and just plain more advertising presence.
Sorry to have such a jaundiced view, but these days I am never surprised at the extent to which media in general, (I was going to say magazines in particular, but really, none of 'em are trustworthy) are willing to prostitute themselves in order to fill their pockets.
Cheers!
