Anyone know of a comprehensive guide to Mercedes cars of the early 70's? Something like Toyotareference.com? I'm trying to figure out what my parents owned when I was a kid. My dad can't remember. I think it was something like a 1972ish 280 or 300 SE, but I don't know what else was available. I've googled, but get too much to sort through, so I'm hoping there are some dedicated sites (with illustrated guides) that might help. Any suggestions would be appreciated. Thanks!
