I have to say I don't think that looks a bad one to repair at all. I work a senior panel repair technician in a large body shop and I repair cars like that every week.
You have to remember most of the damage you can see here is bolt on parts or welded panels which are all readily available in sections and done properly (with correct welding equipment) and measured on a jig there is no problem whatsoever.
You would need to take exact measurements of the strut tops with the jig to make sure the suspension is all going to be within tolerance come wheel alignment time.
I have owned many cat c and cat d cars if repaired properly you will never tell apart from being listed. The problem is some have a go hero attempts to repair something like this on the drive way and it's going to be wrong. Using the correct tools, equipment and quality parts with a good amount of experience is key to a good repair.
