In general the pecking order in classic car prices starts with Open cars (convertibles) at the top, then 2 door Hardtops, then 4 door hardtops (phaetons), then 2 door post (Sedans) and lastly 4 door post (Sedans). Specialty cars like Glasstops, Businessman Coupes, Convertible Skyliners, and Station Wagons go up and down and have their own niche market. For example Station Wagons have recently gone way up in value, whereas a few years ago one could not give them away (except a real Woody of course). Rarity is not the same as desirability. Options can dramatically affect price as well. If a car is in cherry condition and it is desirable and it is rare and it is well optioned then it costs a lot of money. Of special note are survivor cars (no restoration at all). Survivor cars are very desirable mostly in reaction to over-restored cars like one sees on Barrett-Jackson. No mass-produced car ever came off the line like some of those cars.
As the gentleman said: it is a good time to buy. However, even though prices are way down one rarely, if ever, makes money on classic cars. The best value is a fully restored car unless you do most of a restoration yourself or you buy a driver and keep it that way.
Hope that helps a bit.
