I’ve done it several times in the past but since they changed the rules on valuation, I won’t donate anything of significant value. You used to be able to claim the fair market value of the donated vehicle. This was open to abuse and I’m sure many people DID overestimate the REAL value of their donation. Hence the change to actual value the charity gets for the vehicle. However, that means you do not know the true value of your donation until they dispose of it. Furthermore, an unscrupulous person could sell your car for well under the real market value and it would be tough nuts to you, that’s all you’re going to be able to claim.
