As my X-3 28d was over the 50k miles marker and out of basic warranty I brought it to Broad Stroke when the check engine light came on. Chris, the technician diagnosed the issue as one or both of two problems to the diesel exhaust system then Amy, the service writer, contacted a former colleague at a BMW dealership elsewhere who indicated to her that the problem may be covered under an unpublished extended warranty.
At that point the repair shop could have just fixed the vehicle and charged me for it and I never would have known the difference but instead they informed me of the possible warranty and suggested I take it to the dealership, which I did. BMW Seattle then fixed the problem under warranty at no charge to me (kudos to them too for squeezing me in and fixing it promptly).
That kind of honesty, ethics and professionalism in any business is rare these days but Broad Stroke has earned a permanent customer from this as a result and hopefully more customers as a result of this review. These folks are all former employees at other BMW dealerships and really know their stuff! Thanks Broad Stroke!
