BMW Z4 Silver Top Edition

If you live in Japan and have an extra 6 million yen just kicking around, you might want to contact your local BMW dealer, because the German automaker's Japanese importer has just announced a rather enticing special edition.

It's called the Silver Top edition, and is based on the Z4 sDrive23i. It's powered by a 2.5-liter inline-six with a six-speed automatic transmission, but what sets it apart is the color combination: A silver retractable hard-top (with matching door mirrors) contrasting the black body and a red leather interior. Gorgeous, but it's only available in Japan and only 15 examples will be made.
