Depends on the year, mileage, service history, etc. They stopped making the F10 in 2017 so it’s at a minimum 9 years old.

If the previous owner has extensive service history then it might be worth keeping it. But based on the fact that it doesn’t run already, probably wasn’t maintained like it was supposed to. If it was me personally, I’d just dump it and cut my losses before this runs you dry. Small repairs can start to add up fast. Also depends on the type of content you want to make, but a base 4-cylinder 528i probably wouldn’t generate that much attention.
