You know, the SL Restorers Guide book (pretty much a picture book) also puts 12,000 280SL as making it to America, or more than half the total production. They quote 4,000 230SL as making it to America, and 1,300 250SL coming over.
I think that more than 25% of original Pagodas would still be on the road. I mean, they are pretty durable cars and I don't think the James Dean racer/crasher type was the typical buyer.
