666 is the dutch car/janspeed/John rich/Paul Seburn/AllanCurruthers now BenStapley car. When Paul bought it from John Rich he wanted a road car that he could race so the car was roadyfied and re registered, painted white and that is how Paul sold it to Allan Carruthers.
Why Allan painted it yellow I have no idea.
The yellow reincarnation picture I think is at Pardon hairpin at prescott
The rear wing on the "bread van" is a copy of the rear wing that sits on the back of my car (not allowed to use in the mod prod classes though) and the body kit is the same as mine although I assume that they somehow lengthened the rear wheel arches to fit onto the 2+2.
No offence taken rob, re the comments about the look of the car. Beauty is in the eye of the beholder and dont forget that in the 70's nearly every body kit used BIG arches to accomodate wide wheels. With the modern tyre technology there is no reason to run that width rubber anymore
I still think that this is the supposed janspeed race car that some one was trying to sell me in the late 90's
