The "festival of sporting cars" race meeting at Goulburn's Wakefield Park Raceway featured a wide variety of cars in each race, none moreso than in my Dad's race (he's in the clubman #117). In this pic is a fibreglass bodied "Taylorspeed Jem Mk.1" (with Mini Cooper S underpinnings). The Mk.2 has a rear windshield with a squared off bottom. Also note the Australian Mini doorhandles used on this example.
