BGP makes about 200 C8s per day and stores them in the lot
If we consider just 3 days of builds outside, that could be 600 C8s sitting there as a target for that storm.

Most people order the Z51 or other options, so just for numbers I will use $70,000 X 600 = $42,000,000 minimum

Imagine if many of those got some type of damage ?

What does GM do, call insurance company, send damaged ones to mexico, do a parking lot sale ?
Or still send them to dealers and have the customers go through the pain of getting warranty work done or
not finding problems until they take the C8s home ?
