I think good cars have increased 10-20% just in the last year.

A local guy here is on the hunt for a solid 68-70 B body , Last year His original budget was 40k , but couldnt find much. If it was decent it was gone guick.
He has since upped the budget to $50 k and is still having trouble finding a good car .

Not long ago one could find a decent 66-67 hemi car for upper 30s to mid 40s. That ship has sailed. It seems 60s ( and up ) is the new norm if you want a hemi car. Of ANY year .
I know a couple clones were listed recently for upper 50s AND SOLD
