To state the obvious:

IMHO, prices will go up a bit more over the next few years, then flatten out, then slowly decline.

There will be very significant price variation depending on condition and rarity, with the best of the best commanding very high prices for a very long time.

This "Captain Obvious" prediction is based on what happens with most collector cars and in fact most collectables.

Of course, longer-term "macroeconomic" trends are far easier to predict then short term "microeconomic" ones.

As long as there are people around who lusted after a particular 911 when they were younger, and folks of that age have significant disposable income, the market will remain fairly strong. When there are not so many of these folks in the market, prices will soften.

As much as people like to think of collector cars as an investment (as certainly the rarest and best are) much of the market (again, IMHO) is driven by "always wanted one" and/or "gotta have it" emotion.
