Jeeze yeah with price of recycled metal going through the roof, gotta contact our pals at the 1950's MB bathtub/pontoon group to SAVE whats left before it all gets crunched.
Find em here:
http://autos.groups.yahoo.com/group/ponton/
And/or state specifics like yer contact info, city location, name of dealership etc here at Vintage Forum - heck i will post the info over ther at yahoo.com for you, already bein a member of the 1950's ponton MB forum myself.
Plus you oughta be able to cut yer own deal with this and make a few bucks for yer efforts, if thats important. Betcha play yer cards right and dealership will give em up at/near free to you. Then you wanna network em at say $200 each (recycled metal value?) through everybody working with these cars to pick em up.
(edit: You especially being 240D owner understands the value of timeless classics - any 220SE or 190b in the bunch??
