We have one (2013) --- Gwen drives it --- personally I think it's a pig so I don't understand the too much power comment. Yeah 550hp seems like a lot but not given the weight and I don't care for the torque down low either. Compared to my S63 AMG (660 ft lbs of TQ) the Porsche is a big ho hummer....
Having said that --- She ordered a new GTS version for euro delivery yesterday. SHE L O V E S them! Go figure.... tells me it's a soccer Mom's SUV.
