The only thing which really matters is that falling prices opens up the market. Sports car enthusiasts who previously thought Morgans were out of reach will now see opportunities. The market place is rammed with classics for sale. I think one of the issues is that those who are seeking "investment" will try to bale out at the first sign of a diminishing return, and those who are simply "weekends to the pub" drivers will be getting nervous if they think the market is collapsing.
