Well, most dealerships are probably used car dealerships that almost certainly qualify as small businesses. Of course, that has little to do with our current conversation. I'm just feeling extra pedantic today.
Some quick stats on the size of this particular "small" auto dealer company:
Trailing 12-month revenue: $8.9B
Trailing 12-month gross profit: $1.29B
CEO Pay: $2.5mm (for comparison, this is higher than the cash comp of the CEOs of GM and Microsoft)
I'm not sure this business needs regulatory protection from the likes of Tesla.
