There are several standard categories of car buyer: Enthusiasts, poor, luxury, and value.
Vwgti is an enthusiast. An enthusiast has priorities vastly different than the typical Outback, Forester, Impreza Subie buyer. He would probably have been happier in a wrx except for the marginal interior and crap mpg. Mazda 6 would seem to make more sense.
Subaru aims primarily at the value focused car buyer with everything except the wrx/sti. Even the brz is a "value" sports car.
