I am trying to sell my dead brother's Impreza. It is extremely rare, a JDM, STI, 333bhp. I have advertised it in Autotrader and on facebook, but sadly I only seem to be contacted by time wasters. I know very little about Subarus all I know is my brother loved his car and for this reason I would like to sell it to someone who is an enthusiast. Can anyone suggest anywhere to advertise it? Or does anyone know if someone is looking for an Impreza?
