Wouter,

I'd argue that this ISN'T one of the original cars.

I could see a re-paint happening that would change the colour and remove the Superteen branding, I could even see if the RH quarter needed replacing, why the RH quarter panel now has the traditional quarter ornaments instead of the scoops that appear on the LH quarter (and as seen in the original photo).

However, I don't see Barris making one of the cars with round headlights and the others square, meaning then that the fabrication around the headlights on the Alabama car is different than the original design.

Finally, the nose on the Alabama car is much more pointed than the one in the stock photo and the stock photo shows a bullet-style side mirror.

Perhaps a tribute instead of the real deal?
