A great weekend, which started with the small group 1 race - like last year, it was decided to split the group 1 field.
The Simca fight (now all but 2 cars were Simca’s) was a real battle this time, with many damaged cars. Future F1 driver Wunderink won, followed by Mattijssen and Elmers.

The other Group 1 race was won by Rien Frankenhout (Kadett 1900) who had a big lead over his fellow competitors. The first signs of the DNRT Group 1 preparation were clearly visible. His brother Fred was second in the other class (Hempenius won) with the unlikely Mazda 1300 amidst the usual bunch of NSU TT’s. Another DNRT prepared car, of course, though a protest was entered against the forceful driving of Fred.

More excitement in Group 2. The 1150 race was as exciting as anything; after the start, Swart led, followed by van der Pol, Kok and Dijkstra, while van Oorschot had a terrible start (his car was washed before the race - the engine was probably drowned a little...). Kok, now used to the RHD Imp took over with sub-1.50 laps; he had made contact with Swart, who had to give up with a puncture.
Now Dijkstra had enough of it, and passed the others like they were in a different league. Van der Pol had his own problems in between the two Transavia drivers (Kok and the recovered van Oorschot) and fell back. At the flag the order was Dijkstra, Kok, van Oorschot and van der Pol.

Unsurprisingly, the Commodores were not present yet again, but the others had a terrific race. Hezemans had not practised like on Easter (he had other commitments) so he had to start from the back - Chiotakis was on pole, Engeman second and van der Sluis on the front row too.
Hezemans sliced through the field as expected from the man from Eindhoven, but his climb through the field was halted by the brand-new Escort RS of Ernst Berg. While Berg fought with an unwilling gearbox, Hezemans patience was over and he tapped the Ford friendly on the back a few times. On the top of Hunzerug he was finally by, Berg soon retired with a holed BDA engine.
Chiotakis was away at the front, but Engeman and Akersloot had a big fight; when Akersloot finally managed to pass her, but then he dropped back - sand in the injection slides.
Behind Engeman it was van der Sluis who drove a great race and could not be catched by Hezemans. Boshuis was not able to join the fight -

No GT start for the 240Z Datsun in GT this time.
