2007 BMW 6 Series 650i 2dr Convertible (4.8L 8cyl 6M)
I looked at every "similar" vehicle - Porsche 911 and Cayman, SL-Class - but just couldn't find the right fit. I am so pleased with my decision! The car has enough "sporty-ness" to feel like a performance car, but without the harshness or diminutive stature of so many other "sports cars" (I'm 6'3" and 250 lbs). To say that it is in a class of its own is too trite, but there really isn't anything comparable. Thus far it's been a whole lot of fun. I'll let you know what long-term ownership is like.
Substantial agility despite its size. Unparallelled fit and finish. Unbelievable technology throughout the vehicle.
Not a huge fan of the way the brakes "anticipate" a quick stop. In traffic if you flutter the accelerator, the brakes will frequently "grab" thinking you're about to get into an accident. It ends up almost feeling like a stutter.
