We recently bought a 2011 Chevrolet HHR, before we bought it, I didn't pay attention to weather or not there was a place to put a doggie zipline... well, damnit, there isn't. I didn't even think about the fact that there might not be hand holds or whatever those things are! I can't find a pic of what they look like, but it looks flat and when you press it, they sort of glide down, they look like they might be hooks for hanging a hanger up (like ONE, not a bunch). I'll get pictures of it in the morning... its very odd and I've never seen anything quite like it before... I know its probably difficult to picture, but how would you go about putting up a doggie zipline in a car that didn't have actual hand holds?
