So....
This
particular letter shown, is ONLY applicable for that 1960/1961 time period. It certainly matches what was done, sort of, at domestic dealers. Model changeover was in the summer during shutdown, and cars with the following year's model started becoming available in September. Guess this particular note (perhaps there were updates as noted into W113 production) doesn't have anything to do with Pagodas.
My friend owns an MB dealership. He has perhaps the only 300SL that was
never sold; that's right--it was dealer inventory at one MB dealer, and when his family's car dealership received an MB franchise, his father got that 300SL from another dealer. Thus, SINCE NEW, this 300SL has always been in "dealer inventory"; has never been sold at retail, never been titled or registered; yes for like 60 years! Just uses dealer plates!
Though unlikely to be sold anytime soon, I can only imagine some bizarre update or interpretation of this letter, where perhaps if this car were ever sold at retail, someone might try and make a case for my "2021 300SL" that was made in 1959...
Of course those who work at the Department of Motor Vehicles have no sense of humor.
