Not my taste, but. The sound you hear when you open the doors is the interior clashing with the paint. https://www.facebook.com/marketplace/item/315315689556951
Not really my cup of tea but I kinda like it. Not enough to want to buy it but it looks like some pretty good workmanship went into it.
If you're going to do the restomod thing, the details matter. The center of the rear bumper should have been modified/ adjusted or the mounts slotted to bring it flush with the top "tail" of the trunk lid. Bring the bumper up tight to the body. Looks like a can opener the way it is. The interior has to go.
