Is it possible that the seats and wheel arches and wheels etc could have been dealer or factory mods?
No.
If someone wanted better seats the dealer would have sold them a better car. Yours has the trim level 1. Better seats from the factory would have been level 2. A dealer would not go through the hassle and cost of changing seats on the cheapest car on the market, they would have just ordered a car with a better level of trim.
The wheels are not factory.
The flared wheel arches on your car were not even available when the car was new.
A "Leyland Mini" came with no arches and steel wheels with hubcaps
A "Leyland Mini S" came with arches and sports wheels.
A "Leyland Mini LS" came with arches and alloy wheels.
