Use Home Equity to pay off car loan?

[Giro]

I'm paying $30 a month in interest on my car loan.  I plan to pay it off by end of 2017.  DH wants to pay it off by end of 2016, but I'm not in a hurry.  The interest rate is low but I could deduct the equity interest on my taxes.  I'm guessing by using the equity loan, I would save about $100 a year.

Would you get an equity loan for that small amount of savings?  I don't have any other debt. 

No, I don't want to sell the car and buy something else. 

Our taxes are ridiculous and I'm just trying to brainstorm for ideas to save on taxes.

What is the car loan balance and interest rate?  Keep in mind Home Equity Loans and or Helocs have up front fees.  Heloc's interest rates are variable (typically with a "teaser" low rate, initially).
