I'm posting this as I am looking for a Mini 1275GT, which I sold after just moving to Ireland in 1996.
I was a Yellow 1275GT, and had a UK registration umber at the time - WPN778S, which would mean year of registration was 1977-78.
I moved from Wales to Dublin, and was renting a house in Clonskeagh at the time.
When it was sold, it had a dent in the roof above the driver's side, due to a burglar using it as a ladder....
If this jogs anyone's memory, I'd be very interested in re-acquiring this car!
