You have to go back to 86-87 for a 300SDL. 90-91 for a 350SDL.

Warren (turnne1) had his 92 300SD up for sale a while back. A lot of miles but it's in impeccable shape if still available. No LWB W140 Diesels were offered in the US and I think the world.

87 300SDL ... too many miles and too few records for you
