Phileas Fogg, I think you're totally missing the point.
ANY aircraft that may fly into SZD would be business that potentially is taken from DSA. SZD and DSA are both owned by the same company. That company only wants to keep one of the airfields open. If it was to sell SZD, this would then compete with it's own airfield. Why would any business sell an asset that would then compete directly with itself for the same customer?
Business jets regularly use DSA, and they will be paying hundreds/thousands per landing.
Decent business aviation airports have radar or on-site radio navigation equipment (NDB or VOR) - neither of which SZD had when it was open (and which cost of lot of money to install and maintain). Cambridge, Oxford and Gloucester have radar, Gamston has a VOR and others have an NDB. Without these, SZD will not attract anything bigger than a Cessna 172.
