Nick, The "California" part is a nickname given because it's one of the few places in the U.S. where you could leave home without a top and reasonably expect to come home dry.
Cees, Although I take your point. Technically he is correct in that it is the rarest of the series. Fewer coupes were made than roadsters or roadster/coupes. Although he could have left the 230 off the list. I've never heard of a 230 coupe. I am pretty sure MB introduced the bench rear seat with the 250 in 1967.
Doug, According to the SL letter and other sources, the lack of a soft top takes about $4,000 off of the price.
As I own one, I have paid particular attention to these bits of trivia.
Finally, any Pagoda (named for the hard top, not the rag top) in that condition, if the 66,000 miles is truly correct, should be worth $40,000. That's, what, 21,300 Pounds?
