On picking up our Benz

We had a pleasant weekend in beautiful, if somewhat warm, Phoenix (Nephew Rob is in LOVE with the town).
We had arranged to pick up the new 240D on Saturday, May 6, 2006. We received a call from the current owner the week prior to pick-up saying that he would be out of town due to his step-fathers illness, but he would arrange for a friend to get the car to us. I could not believe the arrangements, but agreed to them anyway. His friend was to leave the car at the north side of a Mobil gas station at Tatum and Thunderbird Roads on Saturday morning, and we would find the keys under the passenger seat mat! Needless to say, there was some concern about reaching the car quickly.
