S2000s are already trending upwards. Not two years ago, a nice example was sitting around $10,000; while there are still a bunch of cars in that range, there seems to be a trend of aspirational owners/dealers pushing the envelope to $20k+.
E36 and E46 M3s are doing alright at the moment, and I think the E36 might be "safe" for a while yet...but E46s seem to be close to their nadir. It's tough to find one for less than $15k equipped with a stick. Remember when the E46 was panned for not being a "real M3?" Well, according to common knowledge, those are now the "last of the real M3s."
What's even more surprising is how well the current muscle cars are holding up. '05+ Mustangs, and particularly anything from the '10+ Camaro/Mustang era are selling for way more than I would expect.
Not sure why I know these things. Must be spending too much time on craigslist.
