I get that... but neither of those bikes are "collector" bikes.
The Triumph is a nice riding bike but they made a gazillion 650 Bonnys for a lot of years. Pretty well any one that wants a 650 Bonny probably already has one. They stopped breeding Triumph 650 Bonny buyers sometime around 1964, for the most part.
RZs are at STUPID prices now because of americans, and americans don't want a '85 Canadian "R"... and he has priced his Canadian bike that's in Toronto, that needs a TON of work at California MINT condition RZ levels. If that bike WAS an american '84 model, located in LA he MIGHT get $4,000-4500 USD.
And YES, the sad thing is they will probably sell, to some poor schmuck that doesn't know any better.
And to put my money where my mouth is: If you're looking for "collectable" I'll sell ya a '70 Triumph T100R Daytona, running and certified for $5000CDN or a '89 Canadian RZ with a all new WickedATV banshee motor and Gixxer suspension and SV wheels for $6000 USD (It used to be Gordie Bush's RZ cup bike, but now it has almost 100HP and weighs about 300#)
... or how about a 850 Commando, or a 750 Combat Commando or a '56 Domi 99 or a Triumph TSX or Dave Hugh's TR3 or Brian Henderson's TZ350G or Sharon Boyer's TA125 or a '93 900SS Duc... if you're looking for 'collectable"... get in touch, we'll talk.
