And there you have it, in a nutshell
I think you described the situation very well - as long as there is little potential for the resale value of an oldtimer to more or less compensate for the investment lavished on it, the market will remain cautious. And the main elements that drive values up - exotic brand, fascinating powertrain, sporty (for the era) performance, rarity, and a large and wealthy enough client base that was hankering after these when they were new to be willing to pay large amounts for one - are largely missing. So apart from the Saint one, I see the values remaining well under $100k - unless we are in for a round of massive dollar devaluation or hyperinflation 
None of this will take away the joy of owning one - unless you bought it as a purely financial investment, that is. And older Volvos do have a charm of their own - I did around 400k km in an 850T-5R, which even now (largely garaged and only used for the odd fun road trip) never fails to bring a smile to my face. It is worth next to nothing in spite of its pristine condition but I know where you are coming from with the P1800.
Is Forbes right?

They give some advices on cars, furnitures, wines and... watches. Look at this one: The two " stars " are the Volvo P 1800 and the Patek 175Th Anniversary, especially the Chronograph. I have some doubts when I read that the P 1800 will soon reach 100 000 ...
Interesting advice

On the price of a P1800. If he is talking about a fully restored car disassembled down to the frame and rebuilt ground up restoration I a sure 100k is reasonable as the restoration would most like cost 50k. Great car. Bill
I can say in general

The money you would spend to restore the car to its original like new conditions would be much more than any buyer would pay. But I know you are all about the pleasure and like watches these are not investments but objects to cherish and enjoy. Bill

Yes, the brick. In a European context in the rarest combination, namely black, not yellow, and a sedan, not an estate - I suppose the US would possibly have other combinations. One of only 2500 in total - in this combo it was the only one in the country, ...
