The S2/turbo wings corrode from the inside out and the first victim of the corrosion are the brackets that the plastic underwing trip bolts to. Give this trim a wobble - it should be firmly bolted and shouldn't move but if it moves or feels loose then it is likely that these brackets have corroded away. You will be struggling to find a car with no corrosion at all in this area - well one that's been used well at least.
If those last photo's are of the area behind the rear wheel where the wheel arch rim curls round under the car then this area gets blasted by stones and stuff thrown up from the wheel so it is likely that this area might look a bit worse for wear. Obviously check for any deep or seriaous corrosion in this area but it isn't an area known to be a problem area for corrosion. The typical problem areas as I've gleened are:-
- under the front wing on S2/turbo models (other models have different wings)
- Sills that corrode from the inside out you it is difficult to ispect in this area.
- under the battery in the rear where water can collect if the drain tubes are blocked
- floor pan can be suseptable if the drains are blocked - check for wet or damp carpet
I'm sure others will add to this list, but these are the key things to look out for as best you can in my book.
