Reply #2: There are large amounts of cars sitting on US docks

[customerserviceguy]

and I would imagine that US manufacturers (both foreign and domestic nameplated) have huge lots with enormous numbers of cars sitting, too.

If even one manufacturer held a "clearance" sale as a result of either bankruptcy, or pulling out of the US market, sales for the other makes would plummet temporarily, as buyers went to snap up the bargains.
