Pretty nice. I think this is the same car that has or had a 4cyl turbo motor with a Cosworth valve cover. Both have top mounted wipers, same wheels tires and flares.
The GKN might be more famous but looking at the rear suspension, rear sway bar and the $400+ each per track tire, this car was built to go at the limit and would probably embarrass the famed GKN.
I too wish there was more details.
