❝In 1996, Benefactor had once made an agreement with Progen, to produce the new GP1 V10 Proto. It is powered by Benefactor-Progen V10 and it is tested on a test track.❞
This was made by Benefactor, partnershiping with Progen in 1996, making the car as a work in progress or a customized vehicle. This also appears in a Autoeroticar website. This was currently identical to the 1996 McLaren F1 Mercedes-Benz V12 Prototype, with the cues from the McLaren F1 LM vehicle. This was noticed as a customized Progen GP1 LM with the different cues from a car.
