I don't think that 944 or 928 prices will "dramatically" increase anytime soon. There are simply too many 944s around and the older ones usually need way to much work. 928s go the same way. They will never be an investment, the depreciation curve may slow but not completely stop. Look at 911 prices if you need an example and sad though the truth is, the 911 is the one considered a "true" Porsche. The 944 and 928 are not. 924 prices are not going up or anything like it, just slowing the downward spiral. As the price of parts and labor increases less and less 944s and 928s will be on the road, as has happened to the 914 and 924. Only true enthusiasts, who can and are prepared to run these cars will. Unfortunately, the 911 has an intrinsic value, old 944 and 928 don't.
