The biggest drawback to the 2007 Lincoln Navigator is the engine. The only choice is a 5.4-liter, 300-horsepower V8 that's also under the hood of the Lincoln Mark LT and the Ford Expedition. Its primary competition, the Cadillac Escalade, easily out-powers it with a 403-hp, 6.2-liter V8 that also boasts more torque than the Navigator. And then there’s the grille. It dominates the Navigator completely, and makes this SUV stand out in traffic like a…like a…like a 2007 Lincoln Navigator. If you like the design and don’t mind being seen – and possibly pointed at – then by all means, buy it. But anything that makes an Escalade look subdued by comparison is over the top for us.
