Another discussion ensued, yesterday, regarding the possible modifications to the '64 Impala.
I'm actually quite glad that I got this car, for the simple reason that it gives a whole lot of liberty of action, for when it comes to the actual rebuild. Having modified and tricked out a '65 Impala, and in the process of restoring a '67 Impala to near-stock...having another Impala to play around with lets your mind swim with all sorts of radical ideas, as to how one might rebuild it.
So far some of the things we've thought of, are:-
Body Work
The '64 is a pillarless coupe, which allows you to consider turning it into a coupe, a convertible, or keeping it as a four door. Amongst all of these options, what I think would be most exciting, would be for the car to get suicide doors. Basically, these are doors that open in opposite directions, with the front doors opening "properly", and the rear doors swinging open opposite to their current motion. This should be relatively easy, and would be incredibly striking, too...allowing a wide-open look into the interior of the vehicle. Something like the doors of a Lincoln Continental or Cosmpolitan. Or similar to that of an RX8, of course.
The vehicle is going to be dropped considerably. Ground-hugging dropped, that is. To this end, we going to have to modify the rocker panels and the rear, to keep a perfectly straight line from fore to aft.
I've dropped the idea of chopping off the roof. This car is just too pretty to undergo plastic surgery.
Mechanicals
The current B3 engine along with its gearbox has to come out, and will be replaced with the rebuilt Buick 455 and TH-350 transmission I already have laying around. This is a huge, humungous, beefy engine...which will look really pretty when its "blinged out". What I'd really like, is for it to have a supercharger bolted on...perhaps with a RAM-AIR arrangement. Clearly, if I can get the logistics of this sorted out, the vehicle would be without a bonnet/hood. Just the naked engine bay; showcasing the engine.
Somewhere along the line, I'd also like for this to have power steering, disc brakes and perhaps a limited slip differential. Something to keep all the power in check 
The exhaust would be something nice and growly. A noticeable exhaust note, without it being too over the top.
Interior
Having experimented with fabric and leatherette (in the '65) and leather (in the '67), I'm inclined towards trying something else in the '64. Something...different. Who knows? Fake fur Zebra stripes, perhaps. Or Tiger stripes. Or fractal camouflage designs. Or herringbone upholstery. But something which isn't just single colours. Of course, this will NEVER be at the cost of aesthetic quality. This design cue, will carry over to the trunk, too...which will be suitably done up to match the interior of the car.
The machine will be getting a stupendous sound system.
Paint
I'm still not totally clear in my mind about the exact shades of paint that the vehicle is going to get. But offhand, I'd like it to be a colour against which chrome and other embellishments would stand out. In that way, this Impala is perhaps the most exciting out of all three, since its shape begs to be chromed and blinged and made to look retro-radical.
Come what may, this car is going to be adorned with airbrush artwork. Even if I have to do it myself The inner panels of the hood and the trunk are going to be flat surfaces, and the artwork will definitely extend to these two areas, as well. Perhaps a Devil under the hood, and an Angel in the trunk!
All in all, this rebuild has potential. A lot of potential. And the good thing is, that it's going to take a lazy, unhurried course of action. I'm in no rush to complete this ride. So the luxury of time, is going to be put to best possible use, whilst gathering all the things that are going to be necessary for the rebuild.
Let's see when and how it commences.
Cheers.
