Bill, here is the link for the car "following Tom" in the FaceBook video. I think this is a late model Mustang Cobra. He eventually passes Tom in the 1999 Mustang, but the video sure gives a great feel for the Shenandoah circuit. Tom is beginning to get the feel of the Mustang, moving from a Ford STV Focus - quite different to say the least! Also note the STI that passes the Mustang ....
