I think you will continue to see an erosion in C4 prices. They are still too “new” to have become relics of the past. Another factor that is a negative for the C4 was the volume produced.
Just my humble opinion... the C4’s that are holding their ground are low mile only ’96 Grand Sports, ’93 40th and ’95 ZR-1’s, and the ’95 Indianapolis Pace Car (527 produced). The 1988 35th Anniversary and ’93 Anniversary cars seem to be priced moderately higher if they are low mile cars. Anything with driving miles takes a hit. If you visit the ZR-1 Registry FOR SALE section, you will see relatively low mileage ZR-1’s at affordable prices.

I’ve seen ’96 Collector Editions with 25-30k miles go for a song, they were produced in large volumes. Again, it appears that if it’s a low mile (10k or lower), they seem to fair better than the average CE. I’ve seen GS coupes list for low to mid 30’s with about 20-30k miles.
I’ve been looking at many C4’s lately, most sellers/dealers advertise that they are in mint condition, quite frankly, everyone that has made that claim has had a average or below average condition Corvette. You have to be careful if considering a purchase. Take a knowledgeable C4 owner with you.
