My neighbor across the street has an all original 88 for sale.
This thing was literally driven by an old lady, and it looks just like it did when new.
It has the 455 in it, and runs good... (I am not sure on the mileage, but it is ludicrously low.)
My neighbor snagged it after the old lady died, because her kids didn't want it... now he has a for sale sign in it.
If you are interested, let me know, and I can hit him up about it, and get you some more specific information.
I think he only wants a few thousand out of it, and in the shape it is in, its worth a lot more. (just not my cup of tea)
The car is in Central Utah.

 

If you can get pics please post them. There might be someone lurking about that doesn't post but watches the forums. They might be interested. Hope your neighbor has good luck selling it.
