Legacy GT is a great idea, but unfortunately the AWD Turbo Sport-Sedan/Wagon niche rarely does well.
Mazda Mazdaspeed6 - Gone
Volvo S60R / V70R- Gone (R-Design isn't the same)
Legacy GT / Outback XT - Gone
The only two that remain are the S4 and 335xi. Those cars are in a much higher price bracket than the GT.
We all want an STI in a suit, but it is hard to create profitably. (But I think they should still build it).
I believe the GT could be better and could fit an aging WRX buyer. Unfortunately, it is hard to make a business proposal in Japan when the volume is low and frankly, no one is ever happy. Enthusiasts think they are too weak, and volume buyers don't want the extra power/price.
I have always thought that the Legacy should battle publicly with the A4, 325xi, G37X, etc. Pay some magazines to compare them and show the Subaru is the alternative for people who can afford more. It needs to stop being an Altima alternative and move up to where AWD sedans are appreciated and paid for.
