i have both now - a 997s (911) and a macan S. my wife used to drive an audi Q5, and although they are basically the same car, the seats are so much nicer in the porsche ... and the extra 90 hp doesn't hurt either. i am here to tell you that the macan drives amazingly well although is not a 911 or a cayman. the panamera is just a really big car that also does surprisingly well considering its size - tossable, NO.
i used to think that most other cars were just basic transportation, they didn't drive the way that BMW and Porsche drove ... i think a lot of the current BMW start to fit into that basic transportation mode ... the M's excluded.
