European and even GB prices can be vastly different, this is a new one on me, but not the first "difficuklt" valuation that I have done by far, most bikes have some sort of similar bike selling in recent times as a historical guide, but remeber what people ask is not always what they get, there are a few dealers around the UK that are aslking high prices and not getting the bikes sold, that is until the one punter who will pay it shos up, sometimes more than a year, and in a few cases more than three years.
My own feelings is that this Palmelli, would be on a par with a very good SF2, if it could be proven that the engine had SFC internals, then the price would increase and if an SFC gearbox, then (maybe) some way between the SF3 and a genuine SFC
£9000 for a mint SF2? (they have been going up)
£40,000 for a mint SFC? (they have dropped a bit since the high of 2012)
so Palmelli with stock engine (very likely as most were built from SF2's) £9000
Palmelli with proven SFC internals £20,000 absolute tops, probably a lot less, witness the 750 Egli with (purported) race history that failed to sell recently at £16,000, it (sort of) comes into the same category)
My opinion is that rareity is not going to increase the price much, if at all, top money these days goes to top, stock bikes, lots are returning their modified bikes back to stock, or as near as they can get., remember you can easily buy a stock frame or an SFC replica frame for not a huge amount of money, the rest is bolt on's
In the end its worth what you are prepared to pay, if the seller will accept it.
