I recently purchased a 2008, 650 with 41K. I went for the coupe because I don't like convertible styling on most cars. I previously owned a 2005 545, 2001 525, and 1999 325. So the progression to a 6 was natural. So far it is performing well. This car is a little more front biased than my previous BMWs so it has some understeer. However I can say I get more compliments in the 6 than any other car. People take notice. The V8 in the 650 is better than the one in the 545. I hope the overall reliability is better, but i did get over 210K miles on the 545. Enjoy the car!!! It still drives better than most things out there.
