I'm sure it is at least that much, it also has subframe connectors underneath. My last company car was a 2003 Impala "large sedan" which weighed over 4,000 pounds (adjusted for driver & cargo) on the scales. This car took up less room in the garage than my "compact" (in it's day) Corvair.

I drove air-cooled vehicles, imports (with import motors ;)) and motorcycles for many years and didn't get the muscle car bug until mid-life crisis #1, which was similar to the above, but red.
