There are two places where ground clearance can rear its ugly head. Many driveways and drainage depressions are not engineered well and can gouge the front end. I have a LOT of trouble with that on my G8 and have many scrapes under the front airdam. You can avoid that most of the time by not parking in those driveways, but some streets or motel parking lots are bad. The other thing that can catch you are speed bumps on rural back streets or airport driveways. These are not designed by automotive engineers. Just be careful if you lower the car and think ahead. My wife must drive my cars and she's just using them for transportation and has no clue about little things like dents, scratches, etc. Depends on how much control you have over the use of your car.....
