It has several things going for it:
1) Top boots are present and look nice. That's $600-$800 for a pair, if one needs to source them...like me!
2) Steering wheel doesn't appear to be roached-out or cracked to smithereens.
3) Nice original wheel covers look good.
4) The windows are all down - do they all go UP? Glass all good?
5) The top is down - does it go UP and DOWN smoothly? Is the top any good? Is the center vinyl part of the boot cover present at all (it's easy to get one made, if not)
6) Clear floormat was a period accessory that is worth cleaning up and keeping in the car.
7) I'd look carefully underneath at the floors. And rockers.
8) If you get the car, attack that leather aggressively with a leather cleaner/moisturizer. Use as directed. There are several great sources for this.
9) The dash pad is cracked. These are available new for right at $700. Removal is easy. Installation is a tedious and time-consuming process!
10) Is everything in the trunk that is supposed to be?
Yeah, I get nit-picky on certain things that others may not, and vice-versa.
To me, it's the unknown/unseen element of the amount of overall metalwork it'll need, which is impossible to judge here; other than the obvious exterior sheet metal. NO reproduction sheetmetal is available for the '64-'66 Imperials.
Were I buying the car solely on what I can see from the pics and not knowing the condition of the engine/trans/suspension and the interior and trunk floors, I'd be in it for about $5K. This is contingent on how it runs and drives, and whether the title is valid and in the seller's name. Never, ever touch a "lost title" car in a title-required state!
Ultimately, what is the car worth to YOU??? Is it a fun drive-as-is car for cruises and getting an ice-cream cone? Or are you looking for a suitable car to restore to its 1965 glory?
