I have just seen the trailer and tow rig SMJoe shared a link to for sale...sold. Not sure if the seller got the $87K price he wanted, as the buyer left the mini (and will source their own in the US), but it must have been pretty close, just the trailer was up for $47K.

Caspian Blue '03 BA, Union Jack/Stars and Stripes paint, BUBs, Progressive 812s, and lots of chrome
