A while back I was traveling for business, picked up a white Mustang at Hertz(?) and drove to my hotel. The next moring I went out to the parking lot, saw a white Mustang where I thought I parked, unlocked it, hoped in and was on my way. About a mile down the road I noticed a tan raincoat in the back seat, and since I was wearing my own coat I had a WTF moment, turned around and went back to the hotel to where I had orginally parked the car the previous evening. Sure enough, there was another white Mustang a few spaces over from where I got my current ride.
Upon checking the license # on the key tag, I realized I had the wrong [otherwise identical] car. I put the one I was in back where I found it & locked it up, got in the right car and was on my way, no harm, no foul. This has also happened to a couple of other folks I know, all were Frod products. Go figure.
