Ever since the E24, BMW's 6 series line has almost been forgotten until it was reinvented in 2004. With the newly designed exterior matched to a gracious interior, it is much less disappointing than the same-year Bangle-styled 7 series. Just like any BMW, it drives and handles like an extension of your arm and your leg, even for such a big and heavy coupe. It comes w/ the same V8 engine found in the much heavier 745Li, which screams 325 horses and 330 lb-ft of torque, enough power to get you speeding tickets w/o even noticing, while having decent gas mileage for a V8 (~18mpg city and 21mph hwy). The exterior styling is elegant and classy; where as the interior is also made of high-quality material. It is definitely a sleeper. Long road trip are very comfortable (for front seat passengers); the backseat, of course, for a coupe, is not designed for large adults. So unless you have skinny/short friends, don't expect to seat them in the rear comfortably (that's why us coupe owners won't get asked to drive when we're carpooling in long road-trips right?). Overall, this is a fabulous grand tourer that turns heads.

I have the 645 Ci and bottom line, it is really an amazing car to drive. Absolutely love the way it handles, accelerates very quickly, interior noise is minimal, and the bells and whistles that BMW offers are pretty limitless. BMW offers this model in a convertible as well; however, I prefer the coupe due to the low roofline on the car. By opening the moonroof to show the full glass top, it opens up the feel of the interior...you don't have this option with the CiC.

Beautifully designed BMW. I loved it from the first moment I saw it. I got the chance of driving in a BMW 645ci and I must say it really overwhelmed me. The engine is a pure masterpiece, delivering 333bhp and the well-known BMW sound. It's expensive and has a BMW-style option list, but it's definately worth every euro!

I love this car! Lots of power, to be as heavy as it is; surprisingly nimble. I would recommend this car to any of my friends. It is the sports car for the executive crowd. Lots of luxury, but at the same time will give you a kick in the pants every time you press the pedal down.

I love the way it drives. It's powerful and has excellent road manners both on the highway and around town. I had forgotten just how much fun BMWs are to drive. It's very different from the 500CL that I replaced; sportier. It's unlike my 911; softer. It's nothing like my Ferrari; quieter. Initially I had a difficult time getting used to the I-Drive system. Once I mastered it, it got better. It's still complicated to make some minor adjustments but it's not as terrible as many say. I'll never understand why manufacturers went to run-flat tires. This car would ride and handle even better without run-flats. I'd install them but there's no room for a spare tire. It's simply a great value for your automotive dollar.
