I'm on mile 500 with my cardiff, barely barely broken in so far... Have a b17 special and b72 on my other two bikes- the quality just isn't the same...

I did get it on ebay completely brand new for $40 with the copper rivets (the copper rivets on the seat "wore off" to bare metal on the first ride), hoping it will settle in as it looks beautiful...the underside is not very attractive IMO...
