My father is trying to get back into a diesel after selling my brother his studded/deleted '07 6.0. He bought a 2013 Expedition Limited ($56,000 sticker) I knew this would happen so I tried telling him buy a '13 6.7 F250 beings I work at a dealer I get D plan. Anyways he didn't listen, now 4 months later he found a 2010 F350 6.4 with 38,000 miles Lariat all the goodies he wants. Now working at a Ford dealer i've heard nightmares about the 6.4 yet the few people I know with them haven't had issues. 1 truck specifically 2008 is a local diesel shop owner and he beats the living sh** out of his and just recently dropped out 2 cylinders. He is unmerciful on his truck though so I don't count his as a "normal" ideal 6.4. Do I disagree or go ahead with this for him? Thanks
