Concerns w/ bumper lip height...

Picking up a 428I X next week and turning in my X1. The front bumper on the 428 is very low compared to my current X1. Are there problems with it hitting or scraping on curbs when going up or down inclined ramps like in or out of a pitched driveway or when parking head in?



I will have the Driver Assist Package, does the front bumper have the proximity sensors like the rear bumper to help when parking head in?



Thanks for any guidance
