I just received my new cupholders that I ordered from Griots Garage,
www.griotsgarage.com , They are really cool. Just opening and closing them
is fun.  German engineering all the way.  Their website says these are used
in the MB 500SL.  there is a stamp on them that reads "fischer CBOX".  They
feel very sturdy.  When folded, measures 4 3/4" length x  4" width  x 1 1/2"
height.  Will hold a 12 oz can up to 1 liter bottle. You can install them
with double sided adhesive tape or with the include mounting hardware (looks
like black sheet metal screws, very permanent)  Very clear instructions are
included.    There aren't cheap, $40 for 2 including shipping.  IMO they are
the last cupholders I will have to buy and I have been through a few.  The
