I was born in 1991, and my favorite Mercedes are most certainly not The W210, W220, W202, W163, etc etc.
The first Mercedes I ever drove was when I was 10, and it was a W108 280SE.. I still find that body style the most beautiful Mercedes ever devised. However, my favorite 'modern' Mercedes are the W126 and W140. Also a special place in my heart for a W201... the things I'd do to toss one around the streets around me...
But I do share the inability to discern models of cars years past-- the way my dad can tell from 50 feet at a glance a 1963 from a 1964 Camaro is mind boggling until I put into perspective I can do that with a W126
