We bought this Navigator with 15,000 miles on it in 2005. Motor (5.4 Triton) and transmission are strong. Interior (Leather) is good. AC blows nice and cold. 4 wheel drive works well. Passenger window stuck in up position. You must manually lock and unlock Drivers door. Driver side power retractable step stuck open (door sensor issue). Drivers side back seat interior door broken off, opens from outside no problem. None of these issues affect drivability and usage, she drives like a Lincoln should. Text me for a look and a drive.
