Brian,
I doubt it is 1087. When that episode was filmed we were to provide a car however the car we intended to use was sold so Clinton Ford stepped in with a replacement. The car we sold was in the 106X range and was a fresh arrival so I think 1087 would have been later. Trevor should be able to look up what units went to Clinton and find it. I have a list of the colors that Clinton ordered someplace so it should be possible to narrow down the possibilities.
