No. New IRS rule

You have to use the actural selling price. This is a new IRS regulation.

IRS changed the rule last year. From now on, if your car is valued more than $500, the deduction is limited to the charity's actual selling price. The donor must attach a statement of sale to the tax return in order to receive the deduction. (The charity is obligated to provide the statement within 30 days.) You are not entitled to know the deduction amount before donating your car.
