I don't have one, but I want one. Test drove both the 3.8 and the 4.6 and I have to say the V8 4.6 was a monster! Very smooth & quick acceleration. Amazing braking power for such a big car too. And the sound system is un-real!! It's the same Lexicon based system used in the Rolls Royce Phantom with HD Radio, Sat Radio, USB & iPod connectivity. Very very impressive sound for sure! Amazing car for the money and definitely puts the BMW iDrive system to shame. The central controller is far more intuitive than BMW's IMO.
As for Inception, I thought it was an amazing movie. I definitely need to go see it again soon.
