Even once some of the unemployed get their jobs back, a lot of people will still be left behind. These big events are usually paradigm shifts, so while people expect things to return back to "normal", but rather some combination of factors to make a "new" normal. Also, sales were predicted to be lower this year than last.
It really depends on your time frame. I think this is accurate.
It is always supply and demand. March was going to be a good month with Truck Month incentives. I think sales remained high for Ram because there were many who wanted to buy a truck before inventory ran out coupled with good incentives, so this accelerated the time to buy for some. Supply and demand may be somewhat even as those who wanted/could buy did and are in lower numbers now, just as inventory is. So dealers can put out fluff pieces like that article and it seems true. This is a short term state if production is not interrupted again. Once production ramps up and supplies get back down to the lots, it may start to out pace demand.
