As I'm looking through listings for used and new Stelvios and weighing the usefulness of the different safety options, I'm trying to get a read on whether or not there are any big safety enhancements throughout the model year range. The Static packages and Dynamic look pretty similar throughout the years, but I know I must be missing something. Finally any thoughts on the real-life usefulness of these is welcome. My wife's Mazda CX-9 has a nice blind spot warning that works very well. I've never driven a car with any active safety measures--not sure I'd miss them. Thanks for any info.
