I have a problem with their data. The sum of Silverado's is 401,548. GM reported 574,876. So they are only accounting for 69.8 percent of the deliveries in their so called "80 percent" world.

Honest question. Are the GM numbers including Canyon and Colorado? I would guess that would account for over 100,000 units.

Here is the articles disclaimer.

The numbers in the charts below represent various dealer sales that work with Cars.com and provide us with sales data (which covers about 75 ot 80 percent of all US dealerships) but does not include certain types of fleet purchases which are bought directly from manufacturers. As as result, the half-ton graph below represents a relatively accurate accounting of total sales (but may not exactly line up with other sources of the same data), while the remaining two charts (three-quarter-ton and one-tons) are more in line with those same 2016 results.
