There are good loaner cars out there, I have had many. My dealership gives all BMW loaner cars when overnight service is required. At 5000 miles, these cars become certified pre-owned cars. Most people only have the car for a couple of days and I dont buy they are all trashed. I would like to think the average person that has a BMW in for service is not out trashing a new vehicle for the sport of it....besides any scratches or damage of any kind is payable by the customer. When you take possession of the BMW loaner car, a personal credit card is required at my dealership for any damage including scratched wheels, windshield chips, etc. Besides, with a warranty to 100,000 miles and a loaner car when your car is being serviced, who cares, let them keep it for a month if that is what it takes to correct any problems you might encounter. This is of course my opinion.
