BMW Progressive Activity Sedan Spotted Again With Buick VentiportsRemember the V5 that's no longer the V5? That's because it's now the BMW Progressive Activity Sedan, which is apparently German for "5-Series Fastback." The PAS appears to be on track to compete with the Porsche Panamera, but the tent-like rear camo makes it tough to determine what the rear slope and proportions will end up looking like. We are totally digging the Buick ventiports on the front fender camo...or are those speed holes? [Paul Tan]
