It's a GS Europa.
William Towns got his ruler out again to re-body the Lotus Europa.
In fact it got new front and rear ends but the middle section and mechanics are all unchanged.
It is generally called a Lotus Europa GS today, but I don't recall it being called that at the time or whether it was badged as a Lotus or not.
It was marketed by GS Motor Factors of Bristol.
I believe 2 or 3 were made in 1975.
