For those in the US that would like some kind of MINI luggage but don't want to spend in excess of $300 for the entire set you're in luck. MINIUSA has finally released the MINI Trolly Bag in the US (it had been available in a similar form in the rest of the world for some time). Here's some info from Aaron at Outmotoring.com:

“The newest addition to beautifully designed and crafted MINI product offerings is the Trolley Bag. Designed by DesignWorks USA, a design division of BMW located NW of Los Angelos. These are the folks responsible for the BMW StreetCarver Skate board among many other well received products, cars and motorcylces. The Trolley bag is among at least 3 official MINI products designed by the design teams at Designworks; the bracelet-watch, the city Bag (very cool too!) and the Trolley Bag. It's introduction comes with the stamp approval of the IDSA (Industrial Designers Society of America) with a Bronze IDEA design award. This prestigious award (along with the Gold and Silvers) is given to those products that have outstanding design, concept and execution. The MINI Trolley bag fits that criteria and more. It feeds our desire to move the MINI lifestyle in our homes and emotions.

The modern, yet casual design detailing keep the Trolley Bag a step above the crowd, as the MINI does so well. Soft, wide-track skateboard style wheels, retractable telescopic handle, two mini pockets and of course the large open area for clothing, etc. make for quite a versitile bag. The water-repellant outer layer is made of synthetic material for increased durabilty. Pricing is to be in the 80$ range and should be available soon. As soon they're available we'll try to get a few in for our customers at OutMotoring.com.”
