Here's pics of two Wheels Mags I took last night.
I also have the article with Richards comparing the race car to a black road car too. Can dig that out if you like? Not sure if the black roady was Jim's, the Bathurst pace car, or another privately owned car. From memory, the black and white Vic number plate started with "KB", so I'm thinking it could well have been Kevin Bartlett's.
I'm not sure if this red one pictured is the same car in both images? The pic with a trade plate was the first Aussie test (with handling comparo between other supercars of the time), the second, with full rego number plate, is the top speed comparo at Lang Lang with Crompton driving.
