[quote) Normally I would agree with you martin but as these cars (1-4) were built by ford and not tickford as a prototype they are worth a few grand more! I see what you are saying about mileage and mods though

nicks 500 looks very neat and tidy and i would say its worth every penny i had lol i would love to own it. [/quote]
This information you lot get is wrong.
Prototype number 1 arrived at Tickford from Ford, hand finished prototype, with no particular regard given to road car refinements or the niceties of packaging in the crowed engine bay. So step one was for Tickford to design & build its own prototypes, using manufacturing methods of assembly, for testing & development. It was the myriad small components that needed careful attention, cables, hoses, electrical connections, heat shielding & so on.
Three prototypes were built, by Tickford & the 1st being completed by early April 1986. Once on the road the testing process began & the the three cars went through 10,000 miles of durability running, including 6,200 miles each at 140mph to test high speed cooling among other factors + 1000 miles driven on pare roads, & prolonged idling testing, again for cooling.
So facts need to be put right.
