I'm also 6-2, though mostly legs. When I first bought the car, the seat was set rather high, it hadn't occurred to me to check this adjustment yet, as I didn't notice any real issue with head room or visibility, though the head rail did restrict visibility a bit, it wasn't that annoying.
On the very first real top down drive, I found myself getting pelted on the top of my head by little bits of sand and gravel. This was quite disconcerting, as it was rather painful and was something I hadn't considered being an issue. Of course, it did inspire me to check the height adjustment, and I was relieved to find it went quite a ways farther down, so much that I initially felt slouched into a deep bathtub.
That resolved the gravel on the head issue, though I'm not that thrilled with the bathtub feeling, though it's not nearly as bad now as I thought initially, one gets used to it. To be fair, the tub feeling is still not as bad as the other cars I tested.
