For 1963, following on from the success of the Mk1, Ross and Bob decided to build two new cars using the air-cooled flat-six Chevrolet Corvair motor, along with its four-speed gearbox. This was the era when most six-cylinder cars were a three-on-the-tree column gearchange system and four-speed floor change gearboxes were almost unheard of at the time. These two cars would be a team effort with Ross driving one and Ken Richardson the other

Unfortunately, the Covair engines were impounded on arrival. Corvairs were never built in New Zealand, so the Corvair engines were seen as competition to the major manufacturers, hence they were impounded, and Ross eventually had to send them back to the states

A Daimler V8 motor from a SP250 sports car was purchased and subsituted. For the running gear, they used the transmission from a Citroen DS. Being front-wheel drive it was not too hard to turn it around and put it in the rear. Ross had designed and made the necessary adaptor plate, for the Daimler motor to sit mid-ships.

Naturally, it had to be tested, and as Bob’s farm was next to the Rotorua airport, the car was driven from Bob's farm, down the road and into the airport. Testing was carried out on the runway in between DC3 landing and take-offs. Imagine trying to do this today with all the red tape!

A second car (known as the Mk3) was sold to Jamie Aislabie, who re-named it the Sid Mk1. The rear of the car was adapted by Jim to take a 3.8-litre Jaguar motor and later a 221 ci Ford V8. This car suffered from a lot of chassis and suspension problems since it was never designed to take the extra weight of the very heavy Jaguar or Ford motors. Ken's car was eventually sold to Norris Miles who raced it with some success. And the second car did win the 1972/3 SCANZ Championship.

We can only wonder what if the cars had been built with the 300bhp Corvair flat six and transmissions, as per the original design, it would have been a very different story, but that is motor racing.
