Well what we were told is that currently there are only five in existance (5 were there,however if you count the autoshow car,and the one I saw going in for emmissions I would make that 7)
All were autos with sport shift.They only recently decided to offer manual.
Two new colors
New undercladding color.
Acceleration wise I would say it is comparable to a RS.(not too shabby)
Though the 5 spd should be more fun.
Three trim levels
Fabric interior,5 spd
fabric auto (with sport shift)
Premium,Leather auto moonroof etc...
If you have not yet driven a sport shift equipped vehicle (Legacy GT) I highly recommend it,Very fast and precise shifting,My only complaint is that the shift pattern is upside down,(slap up to up shift and down to downshift,I prefer the opposite.)
I'd be more specific but I dont know what exactly is considered "public" information.
