The best advice is to purchase a 1 owner, certified pre-owned Expedition from a Ford dealership. My 2019 Platinum was like new, 1 owner, with 60,000 miles, excellent service records, came with new Michelin Defender tires, and every bell and whistle you can think of. I have a 12,000-mile bumper to bumper warranty and a 7-year 100,000-mile powertrain warranty, with 32,000 miles and 3 years left. Before purchasing, try every feature, right down to lighting, to make sure everything works, and have the dealership fix what doesn't. Example, mine had a passenger halo not lighting up halfway. Luckily, I caught it because it would have cost me $1200 to replace the headlight housing.
