The TVRs were Griffiths ( V8s, very fast and very expensive) and the Granturas which are smaller 4 cylinder cars and about 15-20 secs a lap slower, but very quick through the bends. The vixens are the 4 cyl road cars that came after the Granturas. Great video, shame you didnt catch the crash as I...
That griff is almost as fast as our GT3 Marcos in Britcar! thats got slicks and wings. we were doing 3.10s in a Grantura.
