It sure is nice to get a legally binding Tax Deduction for a donation for things such as a car. But I like to think most of us are driven by higher motives than seeking to give with one hand and take with another.
To this end I am sure the vast majority are thinking Tax deduction second and prioritizing thoughts such as "what can I do for others".
With this in mind I am certain your search to find the best information on Donating A Car is an ultimately rewarding experience.
