Both bikes look cool. Parts are probably cheaper on the honda, and you probably know more about hondas.
It would be neat to have an OLD triumph, buuuuuut, that one's not old.
I'd tell him what you could go buy for 1700 and take cash in hand, see what he says.
Something like this, " Hey yea, you have a nice bike, I have 1700 cash right now, I can either buy yours RIGHT NOW or go buy this triumph. Either way I'll have a bike today. What'dya say?"
