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