Not that I know of. The price difference would give an indication of the value proposition of a warranty. I've always a assumed that if it is a serious or catastrophic claim, a number of issues come up that could even invalidate DINANS warranty, or BMW's for that matter. Racing comes to mind. Also does a BMW failure, cause a bigger problem because the car is tuned and that has increased the stress on some components. For instance, you are driving your tuned car with an additional 100 hp over stock. The water pump fails and then...who knows what else goes. I'm sure they get sorted out, but there has to be some disputes. Can't be that easy.
