So after many different dealer trips i decided to goto a Cadillac dealer. I was originally looking at an A-4 until I found out they do not have remote starts and a not the impressive interior. Anyways i have found a few different 2015s, all 2.0 turbos. My question is, is there a huge between the "Sun and Sound" package, the "Luxury" package, and having neither? i have found one of each, the S&S is 42k, while the other 2 r 32k. Are there more features to these packages that I am unaware of? Any feedback is welcome I want to be as informed as possible.
