Lincoln's biggest vehicle, the Navigator, is liked by drivers who need to tow a heavy trailer with seven people and their luggage on board. Gone is the V8, replaced by a 3.5-litre EcoBoost V6 that sends 380 horsepower to a true 4x4 system via a six-speed automatic gearbox. If the Navigator isn't big enough for you, there's always the extended-wheelbase Navigator L version!
