I had one of those and couldn't give it away......admitedly this one is in a bit better nick.
That MF was a very rare colour, only ever seen two for sale, this one being one of them. the other one went cheapy and quickly.
Looked like a lot in that film were just unmodded (or at least not obviously modded) racers......I certainly took my halfords Vitesse racer out & buckled its wheels it doing similar things in the 70s before revamping into something sturdier.
