i found a 2001 expedition for 4000 today that looks pretty nice... its got some small body damage but the thing that makes me nervous is that the radiator support is pretty badly rusted. which makes me think that the radiator had leaked for a long time. i havent been able to open the hood yet but does that sound like a to good to be true price or is that about average? its a 4x4 xlt. i've looked at kelly blue book and the book value is somewhere around 6 or 7 but with gas prices i'm thinking actual market value is alot lower. so what do ya'll think?
