Was this once a red car or is that rust proofing under the car?
If I recall correctly the ad stated that the car had just been repainted its original blue color. It is most likely red rust proofing that is shown under the car. I can't imagine it had previously been painted red with the 'bizarre' original blue and turquoise interior.
It would probably help the seller if they showed photographs before, during and after the new paint job and perhaps a video of the engine running on its 'external' fuel supply.
