Guilty too!! I passed my bike test at 16 - 49 years ago!
I have had so many Veteran,Vintage classic and modern bikes it would take too long to list them all - and remember them!
The M3W is for me clearly bikesk( is that a word?)
It helps IMHO to be a "biker" and an M3W owner - but not essential BTW!
Being a bike rider I think makes u a better car driver - safer and much more aware on the road - and the M3W falls into that category.
The appeal to me is the bike engine and the 3W heritage:))
