That Is shocking!!!
I understand the flip side of it as I sold cars for a long time for a prestige brand. As a salesman I wouldn't be taking a customer out on a drive if they had bought a car at another dealer... I would only test drive my customers. Thus if my customer wanted a test drive I would find one in group and bring it to my dealer for my customer to drive. (Arnold shark don't seem to have ANY to drive)
It's that supplying dealers job to get you a car to drive and I get on great with my salesman partly because he knows I won't take any BS, but my patience is wearing thin, especially as I called VW the other day to check on my delivery week, they promised they'd call me straight back and didn't!! I commented that the service from VW/AC has been very poor compared to my previous purchases with Merc and BMW.
