My lease on my 85D is coming to an end. Tesla is trying to get me into a new lease, and found a 100D for me, but without the sunroof, having the glass roof instead. I LOVE the glass roof, but if I am correct, there is no option to add a roof rack. My understanding is that this is only available with the sunroof. I make at least 5 trips to Mammoth a year, and love having the skis on the roof. Yes, I take a hit on range, but it allows me to fill my car with other things (like, people). My alternative is to go with a less expensive 75D and get the sunroof option. Is there a way to add a roof rack to a Model S with just the glass roof? Thanks!
