I'm a member of the same club. Back in the 70s, didn't like BMWs. Ugly, slow, old man's bike. Then in the 90s, knew a bloke with an R90S and started to appreciate the practical nature of them. As
@Mailman says, doing the valves is a cinch. Likewise adjusting the chain LOL. And now the looks of the old slab-sided tank ones have grown on me.
Have thought about finding a nice old one, a 75/5 would fill the bill, might even turn out to the that one do-it-all bike I dream of?

But personally, still wouldn't consider a new BMW.
