WTB....90 or later 300sl five speed

I am thinking of selling my 1991 Porsche Carrera 2 and replacing it with a 90, or later, 300sl. That is the easy part; the hard part is I only want a stick shift. I have only seen one of these at Park Avenue Motors in Palo Alto, Ca about four to six years ago; lovely car. Never seen one for sale used, either.

Any information on these cars and if anyone knows of one that might be purchased would be appreciated.

Regards,

Carl
