The Mecum Effect...Part of the Problem...or Part of the Solution???

This is not new. Barrett Jackson started this many years ago. Everyone now believe they have gold, whether the car is desirable or not.
A guy near me in Central NJ has a 1951 Plymouth for sale for $6,000. The car is solid but needs a total restoration. After the restoration, what would this car be worth?
The dealers and the parts guys should rot with these cars and parts.
