I am expecting delivery to my house on this Friday January 18th. My understanding is the car is first delivered to the Denver service center, cleaned up, and loaded on a flatbed for on delivery on Friday. No Delivery Specialist coming, just the driver. I know we paid $950 for delivery service, but should the driver be expecting a tip? If so, what might be an appropriate amount? I was thinking $50, if anything. I am kind of torn here, as I feel I am not getting the full $950 worth, as up until a month ago I was always anticipating a DS with the car. Your input is much appreciated.
