You've priced it exactly $20,000 over the MSRP on the FCTP Monroney label you posted. The truck has 6,000 miles on it, a $20,000 premium ÷ 6,000 miles = $3.33 per mile that someone else put on it. Maybe even many people. Depending on state, most of demos are untitled and would be eligible for the 2022 iteration of the $7,500 tax credit. So, the new math is $27,500 ÷ 6,000 miles = $4.58 per mile premium over net cost of MSRP minus the tax credit.
