I like the stock 21" wheels better than the 20" wheels, but do not want the low profile of the 21" wheel. Been there on other vehicles and bent a rim. I prefer a little more forgiving profile myself. Too bad Lincoln bundled the 21" wheels in the ultimate package. I did want the 19 speaker stereo system, the LED cornering and headlamps, just not the wheels. I also have to laugh about how they market the start/stop feature of the engine. All I want to do it turn that off permanently! Not a selling point for me, but most manufacturers keep marketing it as something desirable.
