The Z4 is a refined and luxurious convertible, with a power-operated hard top that can open or close in 20 seconds. Power comes from smooth, punchy six-cylinder engines. A newly available seven-speed automated manual works very well. Handling is not as sporty as that of the Porsche Boxster or Mercedes-Benz SLK, but the ride is quite civilized. BMW improved the electric steering from the last Z4, but it still falls short on feedback. The cabin is tight. With typical options the price can easily reach $60,000.
