JGS722V was my first 131 Sport (second 131) in my favourite colour too
The cars's a '79 if memory serves and these pics were taken in 1987. I was 18 and I bought the car in London (somewhere) It had a K&N air filter which was really loud and an ANSA back box.
From the pics it looks like I've still got one more wheel to finish painting....all the bolt on panels had been replaced and then given a re spray before I bought it - yes....two new doors
Even by '87 look at the rear wheel arch - there isn't one.....
I hope you like the pics
