When you think that Mercedes is going to produce 3500 SLR's total and 1,000 Maybachs every year, my 350SD has to be pretty rare. Only 2,066 were ever made, and it was the second rarest W126. The rarest being the 560SE.

My SDL is rare as only 13,800 were made entirely worldwide.

I have a 560SL, which is a roadster, no worries there.

I have a '97 E420 which was only built for one year(but I don't think it will be collectable).

I have a 300SE....But I don't care what the market says about that car. Its a nice one.
