I'm fairly tall (6' 2") and am struggling with headroom in a 2007 A6 Avant. I have to slouch to make sure my head's not hitting the ceiling, and even then I can't see as much through the windscreen as I'd like to. I'm also finding that something under the car is scraping when the road is uneven. Speed bumps I can slow down for, but when the tarmac is bad or bumpy, I can't do much about it. I don't have the car particularly low-slung or anything, but any bobble in road surface makes something underneath crunch. Has anyone else had these problems?
