I'd love to know if BMW "pre-runs" their engines from the factory. I cannot see why they wouldn't. I know that Ferrari takes them on the track immediately after production and runs the snot out of them (you may have even seen their factory show on television recently...BMW and Corvette also had their factories shown on the same series). I can't help but thing the 1200 mile break-in applies mostly to the gears and transmission. Just my guess.
