Klaus-Dieter Hackel took victory in the Historic Final sponsored by Haines Watt from second on the grid as polesitter Mark Armstrong crashed out.
Felix Fisher, starting nineteenth and at the back of the grid in his Reynard, finished second after gaining places thanks to a collision at Paddock Hill Bend.
Mark Armstrong, in his Van Diemen, appeared to start well from pole position but Hackel was able to make a move around the outside of Paddock Hill to take the lead.
Armstrong and Conor Murphy collided sending Murphy’s Mondiale hopping into the air and Armstrong’s Van Diemen across the track.
As the safety car was deployed, Hackel held a five second lead.
The restart, with 10 laps remaining, enabled Hackel to keep the lead with no challenge, as he timed the restart to perfection.
Fisher was still working his way through the field and gained two places in two corners – first gaining at Paddock Hill before making a move at Druids.
His charge through the field continued when he passed Peter Daly, driving a Royale, into Paddock Hill Bend. That moved Fisher into second place, 3s behind leader Hackel.
Fisher started to close in on Hackel, reducing the gap from 3s to 2.199s at the end of the race courtesy of setting the race’s fastest lap.
Daly finished in third place ahead of Stuart Kestenbaum, running in the oldest car on the grid.
Henry Campbell was fifth ahead of Ian Jeary. Innes Hickman finished seventh ahead of Kevin Bottomley, Andrew MacGregor and Steve Venter.
Nicholas Gibson, John Miller and Oke Leuber failed to start the race.
