Engine compartment does have a lot of overspray. Windshield wiper motor, brake booster, electrical components on firewall, radiator, hoses, wheel wells...
On a 1970 Fury with white firewall, wheel wells are black. You can remove them and repaint them easily.
For the hoses, a little brush cleaner and silver paint might do the trick. Otherwise, you can replace. Overall, you may need a few days work to make the engine compartment look nice.
Overspray would lower my bid, but not cancel my offer. I was thinking $7000-$8000
