A year ago we traded our '05 530i with sportpac (purchased new, custom ordered and loaded)in on a new 09 750 LI. We like both cars. Now the question--I'm looking for a car for me--read 650. I love buying new, but it's getting a bit out-of-hand pricewise. And as the car is a second car for me, I'm liking the thought of getting a low-mileage '07 or '08. But nowhere can find discussions regarding the ever-so-slight differences applied to the 650 each year since the intorduction of the 650. About all I can discern is the difference in the rims.
Any help out there...
