I'm looking into buying a used '16 competition M3. I noticed a couple of interest at United BMW, which I understand to be a high volume BMW dealer, and after explicitly asking if these cars were Driving School cars, I was told that yes, they were "Driving Program" cars. At first, the salesman on the phone said it was a leased car driven by a "BMW Executive". When I asked him again if this was a "Driving School" car, he went and checked with his manager and came back and confirmed my suspicion.
Edit- As of 7/21/2017, there are around 20 2016 competition M3s for sale around the country at BMW dealerships, and 19 of 20 are M School cars and only carry the 4 year, non-extended warranty.
Be aware of these cars if you are buying in the used market. In my opinion, these cars are worth a significant amount less than what these are listed for since these were HEAVILY abused cars at M School. Most prospective buyers are probably not even aware these were Driving Program cars. I believe these cars were around 88K new and are selling at dealer auctions for around 66K.
Warning signs of a Driving School car:
1. Used car has the competition package.
2. Used car has carbon ceramic brakes.
2. Used car has around 5-7K on the odo.
3. Used car's CarFax states a leased car, and then shows the car was sold at a dealer auction and "Listed as a manufacturer vehicle" around the 5-7K mark.
4. DMV registration was in Woodcliff Lake, NJ. This is where BMW NA is located
