Sorry for your loss, my prayers are with you.
I have had great experience using WeBeAutos.com
They handle all the advertising, qualifying buyers, paperwork for the sale, transferring of funds and only charge 5% if THEY sell the car. Michael Runnels is great to work with give him a call at (631)339-0399
Worth looking in to. Both of the vehicles I sold through them were smooth, guaranteed sales.
