The cars in the first photo are Porsches, the second one's a Morgan, and the car in the third photo is a Lotus, I think the 101 model from 1989.
Thanks Dave. They also had some old big block Fords. I didn't get to see them race officially, but did see them 'progressing quickly' between traffic lights a couple of days back. Impressive.
There's something about an old Porsche 911 without the bulbous wheelarches...very nice.
