Looks like it worked out! I had a carfax like that a few years ago. Some issue with DMV reporting and ended up being a 1-owner. Guy had all the paperwork from initial purchase with his name on it.
Purchasing my first F-150 tomorrow. 2015 XLT 3.5EB w/ 51k miles. Looking forward to tuning it. Coming from a 2014 Tacoma it should be a huge power difference.
