Hmmm, I don't think it will do much for prices or sales for either "normal" certified aircraft (C172, etc.) or impact the LSA market, either.

There's just not enough intersection between those markets.

The pilots I know that have foregone the medical to fly under SP rules already were flying aircraft that fit the bill - Champs, Cubs, Experimentals, etc. Or had flown them in the past and were more than eager to go back down memory lane and buy one.

Prices might drop a bit for LSA compliant aircraft, but not much. And used non-LSA aircraft are already overpriced for the market.

For new aircraft, it's a whole different demographic going for each type. The CTLS, for example, is a hot little coupe that looks very modern and up to date. People shopping for a Miata or a Fiat aren't really interested in the full sized Lexus or Cadillac of the C172.

The reality of just who owns the bulk of all GA aircraft and their age foretells a huge number of aircraft being discounted to estate sale prices and even scrapped just to avoid future storage fees in the next 20 years.
