Welcome to the forum! Did you take delivery yet? Did they tell you any ETA regarding the sunshade?
Thanks! This is a great community, and I'm rather proud I can be a part of it!
I took delivery 3/30 of my silver 90D, and am SUPER HAPPY with the car. LOVE IT.
Unfortunately, they could not give me an ETA on the shades. The rep said that the shades took a back seat to getting Model X production faster (I'm sure they had pressure to meet the 16K vehicles Mr. Musk had hoped to have delivered 1st Q). But that we would be getting calls as they become available. I doubt any reps have direct insight into production of car accessories from the factory, or whatever 3rd party may be manufacturing them for Tesla.
I'm sure it's worth mentioning to your service rep when you take delivery, or calling to make sure that they have a record that you've requested it. Although they may still call every Model X owner, I have a feeling they may not make too much an effort to contact you if you don't show interest in picking one up... but I'm kinda cynical that way.
