Temporary: supply is down (a lot), demand is up (due to built-up demand) --> prices rise
Long term: demand will pass thru normal then be down (a bit, or a lot, depending on how the recession pans out); supply will either match demand or go up --> prices fall
Its getting to the point, it might actually make financial sense for dealers to put their cars BACK into auction, because they'll make more now at auction, than their current or future retail value. It is indeed irrational at the moment.
