How did you do, investment wise, over the past few years? It depends
on what you bought, of course. We looked at the appreciation curves on
12 models, eight singles and four twins and arrived at some composite
values. The singles include the Piper Warrior, Arrow and Lance, the Cessna
172 and 182, Bonanza V35, the Mooney 201 and for an older classic, the
Aeronca Champ. The twins we examined include the Piper Seneca, Cessna
310, Cessna 421 and Piper Aztec.
Some assumptions: With the exception of the Champ, we assumed a 1978
or 1979 model bought 10 years ago at what the Bluebook calls "average
retail," meaning in the 5 to 7 range on a scale of 10, no damage
history and with engine(s) close to mid-time.
The envelope please: Composite appreciation of those models during the
10 year period from 1988 to 1998 was a respectable 83 percent or an average
of 8.3 percent per year. Not breathtaking, but not bad. (That average
isn’t consistent year-to-year; there are usually spikes and plateaus due
to economic conditions and demand for a particular model.)
Of course, averages are only averages. Some models appreciated in value
more than others. The twins as a group, for example, grew in value by
67 percent, while the singles appreciated by 82 percent. (We tossed out
the Aeronca in the averaging; it’s too much of an aberration.) Yet some
cabin class models, such as the Cessna 421, have easily kept pace with
the most sought after singles.
If you bought a 421 in 1988, it’s worth 91 percent more today than when
you took title. On the other hand, if you bought a 1978 Aztec F 10 years
ago, you’ve beat the inflation curve but that’s about it: For whatever
reasons, the Aztec appreciated only 48 percent.
What surprised us was how much the humble Aeronca Champ appreciated.
If you bought a decent one in 1988—say a 7AC—you’ve more than doubled
your money; the Champ’s value grew by 140 percent. If only you had the
prescience to pick up a dozen at $7000 in 1988.
