Have a very well maintained 6.7 liter Super Duty that was serviced at the Ford Dealer its entire life for regularly scheduled service and maintenance. The Ford Dealer also rebuilt the motor at 250,000 miles and it has an UNLIMITED mile warranty on the Transmission which just had the job done for $5000 so its covered for 2 years with no limit on miles. The truck has also just had about another 6 grand in to fixing a oil leak, new starter, new Nitto tires, air filters amd everything to pass smog plus a new driver seat belt all installed this week at the Ford dealer.
