G8 gt or wait for the gxp to come out. The Legacy would be a nice car too, they hold their value fairly well, plus you could go back a few years and get one that has already depreciated quite a bit, which would be a huge plus.
my vote goes for the g8 gxp, with the six speed it should get low 20s around town and high 20s highway. Have a tune done to it and kiss all those ricers buh bye...
