 Bradshaw's final drawings and a prototype chassis with a wire-frame skeleton built in Pierpoint's shop were delivered to coachbuilder Robert Peel and Company, Kingston upon Thames, who fabricated an aluminium body over the supplied structure using the drawings as a guide.The car was shown to Mini designer Alec Issigonis.The famous engineer was so impressed that he arranged for Unipower to obtain parts from BMC at a price far lower than the replacement retail they would have otherwise had to pay, which helped keep the price of the car low.
