I remember it well, I was a kid in the 80's and I remember at primary school I used to watch the cars go by. About half the cars you used to see were Datsuns and MK2 Escorts with different colour wings, in fact odd wings were very common back then. Also holes in the wings were common.
There is a tiny rust spot on the body work but if the car lasts and passes the first MOT I will treat that.
I saw a lot of the car underneath when my mecnanic jacked up so he could remove the wheel tray (freebie) and it did look fairly bad but nothing worse than the pics above. I have also lifted the carpet up a bit and from what I can tell the floor is very solid.
The sills are also solid, but I am not expecting them to last for two years or anything, all I want from this car is another 6 or 9 months motoring anything else is a bonus.
