This car may have the best design of any convertible on the market. BMW is not known for interior bells and whistles, so creature comforts are sparse but they make up for the lack with exceptional performance and safety. Great trunk room for the size of vehicle, better than stated mileage (31mpg hwy) and once you're in, quite comfortable. Entering and exiting requires a bit of agility but it's a sports car. The 3.0 probably has all the pep ever needed for this size vehicle. The 2.5, that I have is quite functional, just not quite as nimble as the styling dictates but very adequate. Traded a Miata and what a step up. This car fees much more substantial than its size and I love the styling!
Styling, handling, feel, trunk size, ease of raising and lowering top, quietness relative to other roadsters, mileage, integrated rollbars. The quality at used car pricing is exceptional. I'll have this one or one like it as long as I'm able to maneuver in and out of it.
Better cup holders, a little more interior refinement, easier access to console storage, lumbar support.
