I drove a 550 last week, it was glorious. The only other car that gave me the chills like this car was a 2007 Porsche GT3. The sound of the V12 was so intoxicating, the drive unbelievable with the comfort of a 5 star hotel. My question is why arent they selling? Pretty the much the same 20 cars on Autotrader have been on the same site for over 9 months now. What gives?
