I was looking for a convertible for almost a year and considered a lot of makes and models. Every time I looked it became clear that the 650 was my favorite because of the sporty look and the power. This car is a 2007 but almost everyone that sees it thinks it's a 2011 or 2012 which shows how ahead of its time the styling of this car was (not to mention that BMW has only made subtle changes to the 650's over time - but why mess with perfection right?) As for the performance of this car, it does not disappoint. At any speed (the fastest I had it was 95mph and accelerated after that) the car still has power to throw you back in your seat especially in sport mode! The handling is tight but comfortable and you feel like you can take any turn at any speed. I only gave 4 stars for quality because I have problems with trunk button and the soft top gets caught on the bar by the inside window area sometimes when closing. But I didn't buy the car for the trunk and I can live with the little catch of the roof on the inside. The BMW 650 I bought came with Navigation which works great with real time traffic too! The radio is amazing and my 3 kids, 11, 9, and 7 years old are asking me to take them for a ride!
Purchased my 2007 650I in 2010 with 29K miles on it, convertible black over white. Average about 3500 miles a year on the car. The car drives like a dream with plenty of power and braking. Premium stereo can be heard clearly at 100mph +. Consider the car a two seater and forget utilizing the back seat for passengers. As with all BMW's maitenance isn't cheap and if this is your daily driver make sure you stay current with all work needed for your car.
No other car I have owned (Porsche Carrera, Lexus, Volvo etc.), comes even close to the beauty and luxurious ride of this car. Every time I return home I am compelled to utter "God, I love that car." At times returning to me car briefly lost in thought, I will look up thrilled to marvel anew at how beautiful it is. I have never in my many years ever believed I could feel that way about a car. It is just plain fun every day.
