I think one of the things he would have to considert the time for disassembly, re-assembly and servicing the machine after it is re-assembled. This can consume quite a bit of time and has to be done correctly. Also, the application of the decals and price of the decals has to be considered as well as the cost of other materials. Not unlike a car, the machine will have to be disassembled, the surface prepped and then reassembled and customers will expect and good paint job and a good running machine when it comes back to them. A lot will depend on your location and what they market will bear.
