I had the 650 for 12 months and I regret getting it: Too much money for what you get. I paid $90K+, includes: conv, auto, sports pckg, head-up display is an absolutely stupid option, convenience key is not necessary and HD radio that never worked right; dealer said it works best in the city but not in the suburbs where I live, thx and heated seats. I could have gotten a better car for $90K or a great car at a much lower price but not $90K+ for 360 HP. This is my 3rd BMW; I have a 01-740i and a 05-330cic; both are great but the 650 at this price level is a disappointment, not only in lack of HP but in technology/computer etc. Take your time, compare and shop wisely before you commit to a 650.
Excellent road handling, responsive and feels glued to the road.
Computer/Engine Technology adjustable to driver's habit is nonsense if the car can't shift gears and gets confused at a tiny climb/20 degrees - GPS Headup display is truly useless - HD Radio: Discontinue it - Paddle shifters: Waste of space - Insanely a gas guzzler - Lower the price tag
