LEB (West Lebanon, NH) - booked a mid-sized, got upgraded to an Infiniti Q70 with 8K miles. Woof! I had to be in the car for over six hours the next day, didn't mind it one bit. I get a 2-class upgrade if available due to status from a credit card, but this was above and beyond. Kevin, the agent on duty, was extremely helpful as well, and had offered to stay after closing to make sure I got my my car one evening - fortunately it turned out to not be necessary.
