What's the difference between the models at your local Ford Lincoln Mercury dealerships? Mercury wedges itself into the space between Ford and Lincoln. How big is that space? Big enough, apparently, for Mercury to fit six models into its dealerships all based on equivalent Fords. Sedans start with the midsize Milan, move to the ample Montego and then to the traditional Grand Marquis. The small Mariner SUV is available as a hybrid, while the Mountaineer is nicely luxurious. Standing alone is the Monterey minivan. If a Lincoln is too much and a Ford not enough, start by finding your local Mercury dealerships on Edmunds.com and comparing online price quotes.
