I was bumping around and found this movie on the IMCDB and saw it had a Lambo and Kelmark.
The Kelmark if you are not familiar is a 70's kit car based on the Ferrrari Dino. Ususally VW pan/engine based, sometimes a V8 will find its way into the engine bay.
Not sure if the Lambo is a real one or a kit based car. I think my wife went to school with the main actor who drives the Lambo. She went to School in Little Rock, AR.
Car chase 1 hr into movie but I think you see the cars here and there through out.
