I saw one of these Fits last night after my son's Xmas concert at school. Interesting to compare the rear shape of the New Beetle w/ a Honda Fit. Clean break away lines on the Fit. Similar to the Kammback approach.
Here's a weird image of them on top of each other for comparison.
The Fit is Red. The VW Beetle is black. Gets me leaning more towards a kammback design that abruptly stops short of the rear bumper area.
Don't reckon I'll be doing a 15 foot boat tail anytime soon!
