We just completed a refurbish of an Ercoupe. I bought into the partnership with a plane value of $28,000. After two years, we decided to have a complete overhaul and put another $24,000 into it. (Engine, and practically every other moving part).
We insure the Ercoupe for $32,000 which about all the insurance company will allow.
When you consider that Ercoupes that met the LSA were selling for $12,000 before LSA came into being, that's quite a jump.
So, yes, I think there will be a spike. But there are far fewer certified LSA aircraft which really drove up the price. If the plan takes effect (I expect the approval process will take three to five years) and include C150 and even four seat aircraft, there would be so many of them, I don't expect a huge increase in value.
