Long shot - anyone know this S1 RST?

Friend of mine is thinking of taking a look.
I'm not a MK3 Expert, but I've pointed out a few non standard bits

Long shot, but anyone know of this car?

I don’t no the car but it looks quite nice apart from the contrivance in the boot and non-original parcel shelf, Parcel shelf is extremely rare part now without holes

Battery tray and fuse box area are bad rust spots

Limited info in the write up, so just wondered if by random chance it was known.
