If I spent the best part of £100k on a new car and the rad failed pretty much immediately I would be dischuffed. MMC know they fail and have done so over 2 years now, there is no excuse.
An ali Rad on my Roadster costs fitted £825 so probably fitted new not a lot more than the plastic one say £100. That isn't even an option for MMC on the order sheet. I guess BMW only guarantee the engine if the rad is used.
