Wondering if the replacement deck lid is also a flat deck lid, or the later model with the center Ridge?
Condensation doesn’t just happen on outer panels, it also happens in voids, such as rockers and door columns. Even worse, the condensation occurred while being stored in Santa Barbara, which is literally on the edge of the Pacific Ocean, pretty much the best possible situation for creating rust.
I suspect the rust is much worse than what is shown in these photos. Some photos of door jams , the chassis, and the rear suspension area would be of value to evaluate this car.
honestly think you’re going to have to lower the opening price of $85,000, but it’s always easier to come down then go up. 😉
Good luck
