Yes I agree, a very good looking bike that shows all the hallmarks of having been cherished. However not original and unless you retained all the original equipment you took off to "upgrade", sadly not IMO a collectors' bike nor will it appreciate as an investment as much as if it had been original. I sincerely wish you good luck with the sale but don't expect people to be beating a path to your door at that price point. Andy
Sadly I would have to agree with the other comments, amazing bike, superb condition, but not original. As with other Ducati models most want originality.
Collect able or not it is a lovely well looked after bike. You wouldn't get my 12 grand for it mind. I'd only go and ride it. Doh.
