Re: 99 Ford 7.3 Penthouse
I'd recommend getting the VIN, and posting on a site such as TheDieselStop.com and ask for someone to run an Oasis report, which will list all factory repairs and warranty issues. There are quite a few Ford factory technicians on that site who generally are happy to run a report for you.
