That most likely means the car was teal from the factory but the owner decided to paint the exterior white while leaving the 'invisible' panels stock color. (cost savings)
If you check the door jams and the underside of the trunklid, those parts will probably be teal as well.
As for the VWs, apparently some of'em came stock that way.
I'm a Ford guy though so what do I know.
Mine's the red one.
