Hello! Anyone sold a GXP of late? I tried researching the current market value and haven't found much info. I am looking to sell my 2006 Grand Prix GXP. It is loaded w/factory Navigation. Only has 37K. Has the Tan and Black interior. Tried selling on craiglists, but didn't get any hits on it. I have only owned it for 7 months, so I don't want to take a huge it after paying taxes and title fess, etc... I found my dream car, 1969 Camaro for 20K, but I need to sell the GXP first. I need to get $16600.00 out of it. Does that sound too high? After all, there are no more Pontiacs and this is a great car! Shoot me some advice! Thanks!
