The interior looks like its worn well, wouldn't have thought it was a 70k car looking at those seats.
The rust in the boot though, if I was going to fix it with the corner (and it looks like its in part of the seam too) the valance would be coming off as well. You could patch it, but if I opened the boot to see patches, i'd start to question to what standard it had been maintained (which is a shame as the rest of the shell looks to be really good)
