Niel Allen was one of the first F5000 runners here in Australia. His car was in fact painted a light iridescent blue colour, which would be the colour mentioned earlier.
The Elfin Traco Chev
The Elfin ME5
That was his "Team" colour at the time, being used on the Elfin Traco Chev as well as the Elfin ME5 sports car that he had built to order by Garrie Coopers Elfin Sports Cars in Adelaide. Niel only did a few races in the ME5 before moving into F5000.
The 1967 Mustang that he had was an ex Greg Cusack car that he ran for a while alongside the Elfin Traco Sports Car.
