Realistically?
If the car was over here, I'd offer $1OOO. The engine is probably toasted, the tranny looks like it was lifted from an R16 (the shift mechanism on the right side is the arrangement for the sedan it came from, which means that it probably has 4 reverse and one forward speed) and the frame condition is unknown. So, to me, the worthwhile (desirable) parts would be the body shell (a low nose 54), doors, and depending on condition, suspension bits and maybe the frame (depends on how bad/solid). But even then...A lot of work just to get the juicy bits off for renovation with tossing the rest.
I've seen worse...but you have to ask yourself if the renovation costs (not to mention the time and expense of sourcing/manufacturing/begging for missing parts is worth it or just break it up, save what you can, and use that for your own spares stock or helping out a fellow owner) are worth it. 15 years ago, a complete frame-off renovation was in the 35-40K USD range for a car that, realistically was worth 15-20K. This one, though, from the photos? There are some good parts that may be more effectively deployed for saving a car closer to being on the road and in good running condition.
And this is based on my having broken up probably 6 or 7 europas over the years for parting out to various other owners needing unobtanium parts.
Just my opinion.
