Well I am looking to buy my first diesel. I have been wanting an F-250 for a long time now and have finally come across one that I like but am unsure of a few things. I work at a Ford dealer and that is where the truck is at, it has a CEL and a small oil leak that they are going to take care of before I would even consider this truck. The other thing that bothers me is that this is an 06 with the 6.0 obviously and it has NO warranty history in Oasis, nothing at all. To me that seems kind of odd for a 6.0 but then again I've only seen the problem trucks here. Truck has 135k on it and doesn't appear to have had much abuse if any, the only aftermarket things that I can find are different rims and tires but stock size. Does anybody have thoughts on things I should really be looking for on this truck seeing it has had no warranty work done?

Thanks in advance, I've been crawling this forum for months while searching for a truck and love it on here!
