I've never owned pre70 beemers, but still have my R100/7'78 that I like to consider vintage now. Approaching 30 years old soon. Is there a magic marked year for such. I always thought the 25 year thing was it. How about the antique mark? I think different states have different rules applying to this. Is antique over 50? I've never heard in all my years, an exact defined version of either. Thanx.........My first was a 75/5,'72 Toaster, shorty, 4 speed. Wish I still had it.
