You are paying for all the added value from superfluous upgrades and accessories, extra scratches and knocks atained field testing, and the uniqueness of a mega RIF
If you say so. I just don't think off the shelf upgrades change the value that much. In the case of that Bolt the Siegetek gears, mosfet and the lonex piston were a good shout but the rest was unnecessary. Also you can't add cost of labour to value unless its custom made parts.
