Car shape editing problem

[Greyhead]

I hit upon an idea yesterday. I thought it would be useful if I made a "blank" carshape, i.e. one with all the points set to 0.

Step 1: The scale data isn't very useful so I reset them all, going up from 0 to 480 in increments of 16, rather than the pretty random default numbers.
Step 2: I set all the points to 0, 0, 0.
Step 3: Now that I had a "clean sheet" to work with, I made a brand new touring car shape today. According to the car editor, it looks like the bottom picture.

So imagine my surprise when I exported it to the game and it looked like the top picture!

Anyone have any idea what the hell is going on here?
