With the latest Z4, BMW has made its folding hard top convertible more comfortable and refined than ever before. That means it's less of a direct competitor for the Porsche Boxster and more of a rival to the Mercedes SLK. In other words, the Z4 is a good-looking car that's better suited to comfortable, top-down cruising than being an out-and-out sports car. It only has two seats, and limited boot space due to a complicated roof mechanism, but quality is good and reliability should be top-notch.
