I came from an 09 Liberty (Legacy) GT Spec.B. The reason I had the Liberty over a WRX was that the Liberty is much better appointed - nicer seats, better stereo, nicer layout - more luxurious and "classy" than a WRX, yet still capable of going plenty quick. It also didn't attract as much attention (there's lots of Liberties on the road, and the bonnet scoop was much more subtle than that of a WRX), so was quite the sleeper.
The Stinger is a worthy successor to the Liberty for me - it's larger (I've got two growing kids), it's faster, it's more luxurious, and despite the fact that it's much rarer to see on the road than a Liberty, it still has a degree of sleeper to it (there's no brash wing, no obnoxiously loud exhaust, etc).
