I guess it just depends on the dealer and the people. I had the worst experiences with Mckenna BMW here in SoCal, where I bought my X. Savage BMW adopted me soon after......5 yrs now......and I've been happy with them all these years. I've had my share of concerns with my X, but they always took great care of me, even giving me loaners......again I didn't even buy my X from them. The advisors there are all top notch. I've never worked directly with BMW NA on any of my concerns, nor would I.
