Location - San Francisco Mission District
Status - Platinum (match from National)
Booked - i4 or similar (really wanted to try this out)
Received - 430i Gran Coupe

Wanted to try out the i4, and was about to get an xDrive 40, but unfortunately there was an issue with the car's registration. The agent very generously offered to upgrade me to any car in the lot, even up to the X7, but I didn't want such a large car. I ended up taking a very nice 430i Gran Coupe, which worked for me. He mentioned that they usually do have several i4s available, but it was the luck of the draw that day.
