924, 944 as an investment, that's funny!

I think there will be certain models that have good price appreciation, and that in fact have already been seeing some.

Those are the special or low production number number 911s from the 80s. The 911CS for example. Or the factory Turbo Look. Both of those, I believe, have seen price appreciation lately. The '89 Speedster. Hasn't necessarily appreciated yet, but will (at one time, they were highly collected and at $120K). 930 Turbos in general, but in particular, cabs (seems as cars get over 30 years old, the cab versions always are worth the most).

Air-cooled 911s are definately going up in the next 10-20 years. Remember, the 911 is essentially not being produced anymore. The 996/997, with their watercooled "street" engines, problems, size and weight, are just not the same cars as the pre-99 cars. And, the equivalent of the air-cooled 911 never will be produced again. 10-20 years from now, any 911 is that very clean, stock, original and in great shape will be worth much more than it is today.

If your friend likes 356 coupes, I think that would be a good choice for a weekend driver that will go up in value in the future.

As far as other cars:

I do think the 308 Ferrari's will appreciate, even though they are not great cars. I bought a low mileage Quattrovalve a couple of years ago for less than $30K. It seems like today, that would be a $40K car (I got rid of it a long time ago). 308 price appreciation, IMO, isn't based on them being great cars, but more based on their current low prices. Of course, the ones that will sell for the most are the maintained ones - that could kill any profit.

I emotionally like all of Rallyjon's choices:

83/84 GTI. Was such a cool car, and soooo revolutionary to us German car guys who were just starting to drive in the early 80s. I remember test driving several at the dealerships, and being blown away at how much faster and more fun it was to drive than my parent's 320i. I'd love to have a mint condition, original one. They are neat looking and really fun to drive. And you don't see any clean, original ones anymore. But major price appreciation - not so sure.

E30 M3. Very cool car. Was totally outrageous when the very conservative BMW of the 80s came out with it. I do see these appreciating, again, for clean, stock, original examples.

RX7 - I was thinking about those the other day when I saw a last generation one on the road. It was kind of jarring to see it - hadn't seen one in so long. It has a much more exotic look than I remembered. And, it is a lightweight car, aluminium panels, etc. It really was a fairly extreme car, which helped lead to it's demise. I could see those going way up.
