Hey Cd,
I drawed outlines on both a them there autobahnstormers, the VW Golf and MB B, and superimposed the outlines. I was very careful to not distort them, so I'm confident these template images are within 1/4" of the real cars thus representing true shapes.
In order to "Line them up" I had to choose between matching length, or matching height, I chose Height and I matched windscreen tops/ fronts of roofs. It just showed all the difference best.
4 things I notice.
1) The VW is Green and MB Red.
2) The hood area has a dramatic difference.
3) The bottom rear diffuser area is really different.
4) The MB has a few more inches of drop in its roof line and the peaks of the roofs are 12-18 inches apart. When I slid the MB back to try and match roof peaks, something interesting happened as well, the roof lines matched up. So indeed, MB has their roof peaking earlier.
So from the perspective of the roof peaks, the Golf has a lot more sticking out in front, and the MB has more sticking out the back, Hmmmmm.
Hope this helps.
