96' S500, 09' S550
I was considering looking for a coupe and I can't recall what year the dissimilar metal issue went away. I know it was after 1996 because I replaced the one in my 96' because of the issue. I've heard 97' and later were good, but didn't know if that is correct or not. Does anyone know the definitive starting point of when the evaporator is not a relevant question to ask about? I know that any evaporator can leak, but curious about the known issue vehicles. I don't ever want to buy my way in to that problem again.
