Another Nova.

.....and not the British car the Eureka was modelled on.
Steve Rowley's old car was called the Nova 3.

So it was safe to assume that there might be a Nova 1 and a Nova 2.
Here's another Nova. Not sure if it is 1 or 2.

As you can see, the 2 cars bear no resemblance to each other. There is a reason for this. 2 mates decide to build sports cars and go racing. They are both individualists and had a completely different approach to their respective projects. They were built at the same time and they decided to call their cars Novas.
