In honor of the influx of badly-needed new blood to this forum, I thought that I would start a BMW-themed thread. As the title states, what is your favorite BMW, and why?

For me, it has to be the e32 735i, which I consider to be a graceful confluence of old-school BMW big-6 sweetness and refinement, coupled with timeless styling and a reasonable level of amenities. I recall driving a brand-new example 100 MPH one evening on a deserted U.S. interstate and marveling at how button-downed, composed and confidence-inspiring this car felt in that environment.
