Mandingo, your story is a lot like mine. I too owned a X5 (01) and it had way to many problems, enough that I too will never buy another BMW (unless they really change). Plus, the new styling sucks big-time. Bangle ruined (for me away) the few things I did like about BMW. BTW, I still own a 3 series, which has been pretty good and before the X5 I had a 5 series (it was almost a perfect car). I never particularly noticed the styling on the LS430 until the '04 facelift, little improvements all added up and when I test drove one with the sport suspension * I liked it * :D . Add bluetooth, AFS, DVD nav, etc. and it is the best value for a sports luxury model on the market. So far I am really enjoying my ride but unfortunately, the weather here is both sucking and blowing and it seems I can not drive anywhere without being rained or snowed on.
Let us know how you like the LS once you get it.
