I have this recollection of seeing the yellow car in the parked in the pits (by this stage as a "road car") whilst the black one was being raced. Id have to think about the year as i was only a kid then.
The reason it sticks in my mind is that, i recall them trading at at premium at this point possibly as high as $40,000.00.
and bearing that in mind, your car was parked up their, having been roughly rubbed down all over with wet and dry sand paper. and looked a disgrace.
Cant have been more than a couple of years old at this stage
Seem to recall they went to the Big House not long afterward.
