@Stan Galat The sale of the $81k Speedster was over 3 years ago and was an example of a car with all the bells and whistles including a Type IV motor built by Fat Performance . It also came at a time when there were not multiple Speedster replicas listed every week on BAT. Most importantly it found 2-3 people who all thought it was awesome and just wanted it regardless of price.....the magic formula for any car at auction. The next 3 years did not really see any correction but I agree that we might be about to see one. for a brief period.
Not sure why you specifically say "pan based" since originals were also pan based and sell for $250k plus. I think it is more about quality of build than the platform.
