Hi Eric, Tim R here on Georges computer. For 35K USD it would want to be a very nice running bike with all or largely original parts, even if an older restoration. You should be able and happy to start it easily and ride 200 miles in a day without major issues.. A bike should have known history , with pictorial/documentary proof going back a good few years. If it had been "pulled out of a shed/basement/attic" and restored, there should be pictures of it as found if no other paper trail.
A bike which is largely assembled from modern repro parts may be a very nice thing to ride, but should be nowhere near that price, a 45 will be worth more than a 37 cube, a stripped down bobber again far less than a nice complete original bike. An original paint bike is VERY hard to find, and may well go for more than the 35 even tho it may need a motor rebuild and a lot of work. Also check into who has worked on the bike, and their credentials.
Don't be fooled by a shiny paint job.
As a rough guide on US prices, we have seen three bikes change hands for under 20KUSD in the last 18 months that were in need of complete strip down and rebuild but largely complete and running , if roughly. All will have cost the new owner 30-35k once they have been stripped down, everything necessary repaired and replaced, and given a cosmetic brush up, but by no means a full cosmetic restoration to show standards.
If you want an opinion on a specific bike, you would be welcome to email me timraindle@yahoo.com, and I do my best to let you know what looks original and what is incorrect.
cheers,
Tim
