IMO, yes. In March I purchased a 2021 Model X (white, LR, 5-seater, non-refresh). It was a new (next to no mileage) inventory car from Hawaii. It came with all the accessories I came to expect (e.g., tow hitch kit, mobile connector, front license plate holder, etc.) including the front sunshade (fits from the rear-view mirror back). I also immediately purchased the optional rear lift-gate and FWD Window sun-screens, and I'm glad I did. After installing these I noticed an immediate drop in accumulated interior heat inside the car when parked in the (already rising) Sacramento-area sunshine. Yes, I too would enjoy the panoramic view of the front windshield--maybe in the winter. But I will be using the sunshade at least spring-summer-fall. Though the windows come heavily tinted, the Tesla shades really help reduce interior heat. And I believe there are aftermarket alternatives that might be less expensive than the Tesla products.
If you want to use the Tesla windshield shade and your used car does not come with one, check out Craig's List or eBay for your area or out-of-state. I see them for sale once in a while. But hopefully you can talk Tesla into outfitting yours with the front shade.
