Without a doubt, the BMW 650i is the hottest car I've ever driven. You just have to be careful about your speed because as you step on it, you can't feel anything shift... it literally glides from gear to gear like no other car I've driven. I see tickets in my future and I'm not talking about the ones for a show. I had concerns about the iDrive, but I found it pretty intuitive to use and I'm getting more comfy with the voice commands. All in all, the car is a beautifully tuned machine. The front end of the car is a lot prettier in view than the back end. But then the "not so pretty" back end gives the car a hint of less pretentiousnes with a really big trunk.
If you can afford this car and want a FAST, great handling coupe, go buy one. My old BMW doesn't even compare to this car. You won't see very many on the road and heads will turn when you drive by. I can't say enough great things about this car.
I bought this car because I wanted to know what it was like to drive on the autobahns of Germany at speeds they were intended for, and the 650i lets me do that. I haven't had to pull over to the right lane for anyone yet. The acceleration, whether starting from a stop or at 100 mph, pulls you into the back of your seat. Merging and passing is effortless. The car grips the road at top speed (157 mph), around corners, or even on wet surfaces. It makes you feel almost too safe..... I used to be a Mercedes guy, but I have definitely switched. This car drives so nicely and smoothly, has such a simple elegance inside, and turns heads because of its awesome exterior. I am 100% satisfied!
