Total Vehicle Sales vs Lightweight Vehicle Sales
Vehicle Sales Month Over Month
On a month-over-month basis, sales fell 32.15%. On a percentage basis, this is more than 987 but less than the 35.37% decline in September 2009.

I expect the unemployment rate to hit at least 12% in April and more likely something close to 20%.
A deep recession is coming up.
