I have yet to scrape our new MS3 but that's due to slowly angling every entry and exit that looks scrapable.
In my former life as a valet parker, I had to warn all "sports car" drivers of the steep decline exit from the hotel where I worked to keep their front ends intact. One Lamborghini Diablo driver installed 4 solid casters under the front lip to prevent scraping. They looked like skateboard wheels that were attached to the frame and essentialy took the brunt of the impact on low surfaces and lifted the car enough to allow it to "roll" over any steep incline or decline without scraping the body. I do not recommend this - merely an observation.
