I have a 2003 Cobra that I am thinking about selling so I can purchase a used Raptor. What are some of the things I need to look for when purchasing one? I am looking to spend around 35k or less and have seen a few going for that. Examples on ebay now 2010 Supercabs with 5.4's. I was thinking that I would like to have the 6.2, and later add SC.
