Some guy with a strong Indian accent claiming to be from GMAC. My wife and I had an account with GMAC a while ago, but we resolved all our debts with them and then closed the account. No more business necessary.

Big red flag.

These people are not only calling, they will send letters trying to make it sound as if the IRS are after you. They want you to send your SS#. Don't respond to these people. They are using "GMAC Financial Service" in the letter.......
Watch carefully! Call GMAC Corporate to verify!!!!!!

Possible scam...says you have unclaimed property (in this case a check from 2003) and to return the filled out form to get the cash.  Left 3 messages.  Never talked to a person. Recording said they would get back to me within the next business day. Never got a call back.
