Apologies for asking the answer for resolved questions. From the answers it is clear that personal auto loan is not tax deductible. I live in California and I own a home. My credit union says, If I pay $200, then they can make my auto loan as home lien, which will make my auto loan tax deductible.

Is it legitimate to do so, or is my credit union doing something fishy? I am kind of concerned after seeing the earlier answers.
