Vehicle History


Having been owned and held within the same family since it was built to order in 1974 until 2018. A fan of the Cooper S, the vendors wife wanted something a little more special and with a brother trained as a mechanical engineer, they together decided to create, what in their mind would be, the ultimate Mini. The project to build this car began in earnest in July 1972 when £85 was spent to purchase a rolling Austin Mini shell (chassis number 918077a). Built to order, receipts are present for virtually every item used, in a lovely history file.
