Hello Jason,
It's my own dealer, they were not keane at first, but when I made a whole programm for the day, they said that they would try it.
After the dealerday they were very enthousiast, they say it was 300% better than expected, so we may come again.
They checked all cars from top to bottom, give each member a list what was wrong on the car, and they get a certificat.
Also they payed for cake, coffee and lunch, so it was a nice day.
Hope you get also a dealerday in your neightbourhood.
