Well considering a "GT500KR" was used and not modified in any way on the exterior except for the scanner then it wouldn't be hard. Nevertheless I think anyone that owns a real GT500KR could care less about Knight Rider and probably bought it for the car alone and not as a fan of the new show.
As many have mentioned you don't need a real GT500 to make a replica, it's a replica after all. Us making KI2T replicas sometimes...corrections many times don't start with an 82 Trans Am.
Anwyays I made this post on the Registries a while back if anyone wants to delve into building their own KI3T. Even though I'm not a fan of the new show it might help. Granted this is for the "pilot" KI3T but a lot of it works for the current car. Oh and you can always get the center vox globe from Taoworm
In one of my insomnia filled nights back around when the pilot episode aired I tried to figure out all the stock parts you'd need to buy to replicate the pilot KR3K.
Some parts have obviously changed how the car looks now in the most recent episodes, but I just found this document in my harddrive while looking for something else and thought I'd post it up now. I didn't update the list to see if I found better parts like the seats but I did make sure to see if all the links worked.
As much as I despise the car I was bored. Here are all the parts you'd need to make a regular Mustang look like a GT500. I was curious how much it would cost in comparison to our replicas and got a little carried away.
So I guess if you have a Mustang laying around that you'd like to turn in to the pilot episode KITT (*cringe*) here is a good start.
Mustang Depot has nearly every part and for some you can just get it straight from Shelby or Ford. Or look around, a lot of the parts are sold in a lot of places on the net.
Mustang GT500 parts:

Hood:

Seems that they have 3 very similar hoods
TF10024-A53
TF24-A52
TF10023-A44
I don't understand how that first one only fits the GT500 bumper though, which by the way you will need as well.
Front Bumper:

Rear Bumper:

M-17835-C
Also found at Shelby
That and a few Cobra emblems also found at Shelby and that is all you need to make it a GT500KR don't forget the stripe kit too. You can find that at Mustang Depot too.
For all that you're looking at about $3,300
Now if you want to do the Attack version I guess you'd need a few extra parts.
As far as off the shelf parts there aren't many.
The side scoops:

The show ones are a bit boxier and stick out more, but the SS-950-70737 look pretty close. Although if you look at the movie one the scoops extend to the door and there are no door handles. Maybe take a few and cut the ends off to make a big long one.
Blackouts:

Or Mustang Depot sells some as well
I can't find any flush quarter window side scoops that have the single inverted vent in them, but they don't seem too hard to make. Maybe modify these?

The front "armoured" grill insert is custom although seems fairly easy to fabricate.
The rocker panels/side skirts are also custom. These look kind of close:

The front headlight bar thingies (that's the best description I can come up with. I have seen pictures of cars with the bar thingy without the part that extends to the side, just the bar for the headlights, but I can't find any places that sells them. However, contact GAS maybe?
http://www.galpinautosports.com/accessories.php" onclick="window.open(this.href);return false; Look at the red Mustang.
If not they don't look too hard to make either.
Spoilers:
Mis and match bases side plates and wings

Look around, they're universal style wings. You can probably find them locally at a tuner shop or on eBay too.
For the interior
The wheel and as I mentioned a long time ago it looks to be a variation of the Millenium Evo, maybe the new version looks more like the show one and the one on the following link is an older wheel because the grips of the show wheel are slightly different.

If you look, the grips of the show one look like the grips of the Jet style with the Millenium Evo center.

Aluminum dash kit:

You need some aluminum Mustang sill plates. Mustang Depot sells some Shelby ones, but the ones on the show car just said Mustang, I"m sure you can get those from a local Ford dealer.
Seat Belts:
At first glance I thought the seat belt harness on the car was an actual Sparco one, but it just seems they took some Sparco logos and stiched them to some OEM style belts. You can get some Sparco seatbelt pads or something. Or maybe it is a silver colored Sparco harness

*FYI* If you do put a harness in your car make sure you put a harness bar in your car to attach the harness to. If just bolted to the floor or seats if you get in an accident it's bad news.
Everything else seems custom.
Seats:
I must have searched thousands of seats from Recaro, Cerullo, Bride, Sparco, Corbeau and cheap knock off ebay seats you etcetera you name it. I finally found the following Sparcos (I'm linking to the cheapest I found them)
http://www.saferacer.com/sparco-modena- ... ductid=786" onclick="window.open(this.href);return false;
They're not even on the Sparco website. If you look closely at the following picture
http://img158.imageshack.us/img158/2276 ... be7gt5.jpg" onclick="window.open(this.href);return false;
You'll see that the top of the seat on the backside it looks a little rough. I think they took some Sparco Modena seats and cut the top portion off where the Sparco logo is and had them reupholstered. There are no other seats I found that had the same harness cutouts.
http://img409.imageshack.us/img409/4474 ... e0aop8.jpg" onclick="window.open(this.href);return false;
If these are not the seats than I have no clue what else they can be as I literally must have looked at over a hundred pages and 10 or more brands of seats. I do have my doubts as the center stitch pattern is different than the ones I linked
What's up with the metallic thingies on the center stack?

Check out more pictures out here:
http://jalopnik.com/photogallery/kittbrooklyninterior1/" onclick="window.open(this.href);return false;
Whatever they are it just seems they took some metal things and cut up the stock dash pretty bad.
Then the weird fiberglass thing in the middle of the back seats which is obviously custom.
Engine stuff.
Looks like they installed a Whipple roots style supercharger. You can get that here.

That's about it..I listed pretty much all the off the shelf parts you can get to start a pilot replica if you so dare choose.
I doubt there will ever be any sort of market for replicas like there are for the original KITT since there really isn't much there to do that would require special parts being made, aside from the scanner oh and I guess the underside shielding with the neons and KR. But over all, nothing that yells out "iconic", it's just (yeah just, heh) a Shelby GT500GT Mustang and has been an icon on its own for decades. If one were to make the Attack Mode for some reason then well that'd be different. I better stop now or I'll start rambling about the stock interior...
. I think that if someone did it right it would really be awesome as I doubt anybody would have the balls to use a real muscle car and not some 6k used mustang 
90,000 Dollers?! They're worth that much? 
) only problem with these cars is that they dont really fit KITT, the way the Mustang has been protrayed and maybe its just me but the interaction between KITT and Mike and other actors in the new series it's hard to imagine KITT as something other than a Mustang in this series. But, like I said maybe it's just me.
