They built about 90 TVR Grantura Mk 3 cars. Mine was a 1963 model that I raced for many years.
The story of the restoration of that car as a race car can be seen HERE
They made excellent race cars - here is a track test from the Sports Car Graphic, January 1964 issue HERE
I have sold my car to a chap in Holland, as due to lack of time, and the fact that I have another vintage race car (1958 MGA Twincam), I hadn't been using it for a few years.
Below is a picture of the car now happily racing in Europe.
