2008 BMW 3 Series 328i 2dr Convertible (3.0L 6cyl 6M)
This car has fantastic handling. It is well-balanced, and the steering reacts almost immediately. The interior is well-designed, although iDrive is still a pain. I have the convertible, and, if I had to do it over again, I would not buy this car. The miniscule trunk with the top down makes it impossible to run even minor errands. I cannot even remove my tennis racket without going through the machinations of putting the top up. Even more frustrating is the harsh ride inflicted by the run-flat tires. I changed mine to regular go-flat tires one week after purchase, and the ride improved immeasurably. Overall, a nice car, but the trunk space and run-flats ruin the experience.
Engine, suspension, and nicely designed interior.
Do away with the hardtop and go back to a ragtop with a real trunk. Junk the run-flats. Improve the mediocre stereo.
