How is ground clearance a disadvantage? Are people really gonna go rock crawling in the FX? It's not you are making it as low as those cars that will scrape their bumpers. Hell, I barely even scrape my front skirt on curbs when parking. Happened maybe 3-4 times. G sedan however, every time I park.
stu, im not lowered but ive managed to scrape a couple of times in poorly designed parking garages and also a lot of my friend's driveways (steep driveways are very popular here... maybe to save space). Just a fyi, but i agree that generally we wont have to worry about ground clearence
