Critical pics of prone rust points are missing. A PPI by a knowledgeble person would be my advice.
you can drive it with a bit of rust, with a lot of rust even, but the value of the car depends (for me) greatly on something I can't asses based on these 222 pics.
Missong from the toolse are the small and large red screwdriver, small pliers and some open and closed spanners. 200 to 400 euro max (if you want them tomorrow) and it would be a complete set.
It still has the scarce 10 mm allen key, wheel pin, and the large pliers.
Rest of the car seems to be assembled and painted quite well. Nice door gaps and flushness.
If build to sell, then i agree that getting these last bits right make the difference between a nice car and a flawless car. I'm noting also the fairly dull ("patina-ed") door latch and trunk catches for instance.
If the restoration was done on a tight budget, these misisng trunk tools are fairly easy to add later on when funds become available. As are a few of the shiny bits that could benefit from a fresh zinc coat.
Someone's going to have a nice car. 61KUSD seems about right.
