Well, I guess that I qualify as a Youngtimer enthusiast myself. I currently own :
1976 2002 (Schwarz)
1983 320i (Schwarz)
1986 325 (Alpineweiss)
1987 MB 190E 2.3 (whatever the MB white color is named)
Just sold another 325, a 1987 in Burgundrot.
My only concession to "modern" cars is my Oxford Green 1997 528i, which I bought three weeks ago. Wasn't really looking for one, but the deal was too good to resist.
I am lucky because I get a company car (currently a 2005 Ford Escape XLT V6), so I can keep on buying and fixing up older cars!
