Im sure you are right about the name (and the colour) attracting a premium. It seems that certain marques of any vehicle are always that bit more expensive than perfectly acceptable alternatives. Also as time goes by they become more and more unaffordable. As an example, some years ago l had a red Porsche 911 sc targa which at the time was not the most desirable model. I eventually sold it for £4000.00 . If you want one today and if you can find one it will be £30,000 or there about. By that token l have a Ducati 748s monoposto (also red) but lm hanging on to it even though riding it frightens the whatsits out of me !
By the way what was your red Bianchi like to ride ?
