BMW has made the fastback shape before, it's not new. The 5GT is ugly, but the 3GT isn't horrible looking. There's really no reason for it to exist, though- has none of the utility of a wagon and doesn't look as traditionally nice as a sedan - just about as awkward as the X6. However, the thing that Americans forget in their America-centric car society is that in cultural centers of the world, it's not that cool to go buy what looks like a corporate-owned fleet car (just about any BMW, Mercedes, Audi, Volvo, etc sedan - the larger ones driven by chaffeurs) - and having a wagon, an SUV, a sports car, or one of these alternate shape cars (A5 Sportback, 3GT, etc) promotes the separation between personal choice and company privilege, and that is true status. Big sedans are stodgy, the real sports cars are too showy for most, SUVs guzzle gas and aren't fun to drive in small backstreets, and are less refined - thus it always comes back down to small personal coupes like the M3, 911, or practical family wagons like the 3/5er touring, the E class wagon, etc.
