I think the car you are asking about is Tom Savi's Buick Regal. Tom built several hand crafted fiberglass cars over the years, including his red #28 Ford Thunderbird Sportsman, which was a very popular car. When Tom moved up to Modified, he built the Regal.

West End is/was a Fairgrounds track in PA. I never got there as we were off with MicroDirt running Snydersville during that time period. It looks like a great track!
