Nice looking car. I really like the blue on blue.
If it was stored in a protected environment, the hoses may not be deteriorated badly. How do the hoses look that you can see in the engine compartment ?
Brake calipers are a concern, as they may well be stuck, or will, after a few applications.
Hopefully, there is a high enough anti-freeze concentration to ward off major rusting in the block.
I would check out prices for the parts that it may need and, of course, all the fluids and flushing chemicals necessary.
WAG ?? No idea but tires and a battery are going to run 1-2k. Friggen batteries are $2-300 now..
