I also wonder how that affects what the total amount 'billed' ends up being. For instance, if BMW corporate is footing the bill for all the maintenance/warranty issues for the first 3/4 years of ownership, are they more likely to 'repair' minor issues without asking the customer? Where as say a Volkswagon owner may not bother to have the dealership spend 3 hours diagnosing a squeak or minor rough idle knowing they have to foot the bill?
