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