Just to clarify my opinion: I don't disagree with most of what Bill and Royson have said. The part I do disagree with is the statement: "Year does not matter, Tim. There is not enough difference between a 1968 to 1977..." From a flying standpoint, this may be true--similar cruise, similar stall, similar t.o. performance, etc. From the viewpoint of price however, a new plane is generally worth more (at least in my calculus) than an older plane in similar condition, equipped similarly. That's where our two opinions differ. We're talking generalities here--unlike some commodities, airplanes have so many variables that providing an exact number for a price is almost impossible without a very good looksee. I am sure there are 68s that are worth more than many 77s--it all depends on the variables of each.
