"....my wife was not insured to drive the courtesy car so you arranged to drive my car home and to collect the courtesy car. My wife says that you were very understanding and flexible on the telephone and I'd like to thank you for that.
Both my wife and mother-in-law commented separately to me that the gentleman who came was really professional and friendly and made the handover easy....."
"I hope you can pass my thanks on to whoever it was that delivered my car."
Thanks again, Jim
