Those ridges follow arount to the sides of the Flex as well. They are actually much larger than the small ones on our Crossfires, maybe on the order of an inch across! The Front doors have the same ridges in them...maybe the rears too pretty soon.

I've been out at Oakville assembly every Thursday-Sunday for the past month doing weld support for the Flex.

Actually, I think it'll be a pretty interesting vehicle. Big, But it looks to be built pretty well.
