Avoid middlemen. Numerous for-profit intermediary
organizations advertise aggressively on TV, billboards and elsewhere,
offering to help you donate your car to charity. Here’s the catch:
These organizations typically keep about 50 percent to 90 percent of the
car value for themselves, and the charities don’t get what they
could have gotten.
To prevent this, check directly with charities you
admire and find out whether they accept car or boat donations.
