One datapoint of a sold Porsche, and a couple datapoints of some CS's selling for >$100k, does not make a trend.
Prices are up (yes, even in this pandemic) for quality cars. Folks are cashing in on their 401k and they're now buying their dream cars. Done cars are appealing. Who wants to spend 3+ years in restoration with all the hassle when you can just turn the key and drive?
However, just on observations...
W113 Pagodas are kind of flat, #2 cars averaging $80k
Long nose 911s still creeping up. 964s, 993s kinda flat
E9s are steadily going up
E10s are steadily going up
musclecars are flat. Maybe going down some. Same w/50s AMerican cars (TriFive Chevy, DeSoto, Caddys).
Trucks are slightly going up. SUVs are going up (Broncos, scounts, early blazers, Wagoneers)
Old exotics (Gullwings, Dinos, early Ferraris, Aston Martins, 427 cobra) kind of flat except super rare ones (GTOs, 275GTB/4, Miura S)
Four-door sedans steadily going up (M5s, 500Es)
240z steadily going up.
