"Mazda may tout the Miata is the &amp;quot;most-popular&amp;quot; roadster based on sales, but when it comes to roadster heritage very few companies can touch BMW.  When it came time to test the newest BMW drop-top, the 2013 Z4, XCAR decided to trot out a full collection of BWMs from its 80-plus years of auto manufacturing. What follows is an intimate look at the troubles, stumbles, inspiration and greatness that has been created by the German marque. From the roar of the 327&amp;#039;s flat-six from the mid &amp;#039;30s to the bonkers engineering behind the Z1&amp;#039;s disappearing doors, there is plenty to see and hear in this new video.  The video is a little long (with a run time of 23 minutes), but if you can snag a long coffee break, its worth every moment.      "^^<http://www.w3.org/2001/XMLSchema#string>
