2004 BMW 6 Series 645Ci 2dr Convertible (4.4L 8cyl 6M)


Review

This is a magnificent car, providing more niche-fillers than any other car on the market: a true sports car, with excellent speed and handling, top luxury, eye-catching look, available with a stick, and a back seat and trunk that are actually useful. However, the alloy wheels are so soft I'm on my my third set, and despite their advertising, BMW will do anything to avoid having the warranty cover anything more than the usual minor issues. The software on the care is unreliable too and the car is a gas hog. Even so, I love it, but it's hard to accept being treated poorly by BMW given the nature of their advertising and the cost of this car.

2004 BMW 6 Series 645Ci 2dr Convertible (4.4L 8cyl 6M)


Review

This car is not the best in any category, there are better looking, faster, cheaper, whatever the category. But as a package, this car is the one to take out on a winding road on a Saturday afternoon. Or you can just drop the top and actually enjoy your drive to work, as I do. It has all the power you need to be pushing well to the right side of 100 by the end of the average on ramp. It sticks to corners like glue. And yet is behaved enough to not look like you are finally living out your high school fantasy - even if that is exactly really what you're doing.


Favorite Features

Big 8 has lots of compression, makes downshifting the auto a lot of fun to use when attacking the corners. Something you can't do with a smaller engine. And it has just the right level of engine growl to make going under overpasses or tunnels make you grin real wide.


Suggested Improvements

Surface more basic controls. iDrive really isn't all that bad. But being able to adjust vent levels easier while driving is harder than it needs be. I miss the real time mpg readings. The car can achieve decent mileage if you behave yourself. Behaving yourself if just the hard part.

Review

I have owned 6 BMWs in my life starting with the 2002tii in 1974 and continuing through a 530i, 633csi, 740iA, 745i and now the 645. It is by far the best car I have ever owned and still makes me smile after 2 years of driving.

Review

Love to drive my 645 when the roof works which is not very often over the last year. BMW can't fix it after 4 attempts on my nickel and I can no longer afford these repair bills. Like some women, this car looks absolutely terrific, but don't even think about getting too close. It'll cost you! There are other cars out there that are a joy to drive, do the right thing - buy a coupe!


Favorite Features

The lines are beautiful, interior is comfortable, and it drives like a true BMW.


Suggested Improvements

Please fix the convertible roof so it works after 2 years. Correct the engine lag when in manual or don't offer a manual mode.

Review

A blast to drive - can't leave it in the garage and take the Lexus!


Favorite Features

Sheer acceleration - but the brakes are phenomenal!


Suggested Improvements

Including a rear seat wind baffle as standard rather than a $570 optional accessory would make noise with the top down much less an issue. Too much buffeting with the top down over 70 mph.
