1. Color. Go with the Blue - it looks way better than the red. Even though there may be no data to support it, it feels as if red cars are pulled over more often than the other colors.
2. Protective film. If you can afford it, the full body wrap sounds great - you can change the way the car looks and can go back to stock at any time. After eight months, my black S has some scratches, but I believe they can all be removed with good automotive detail, so you could save your money.
3. All-Glass Roof. I have the Pano roof and love it - but I like to open it when the weather permits. I have seen the all glass and it is fully tinted and makes it so that if you are tall, you have more headroom. In your case, I think you should go with the all-glass roof.
4. Subzero package. The only thing I miss from my Nissan Leaf is the heated steering wheel (yes, even in Southern California) - I think the package is worth it and I always include this package when I am building out my future Tesla. You may go to the mountains someday and in that situation, you will be glad you went with the package.
5. Premium Upgrades Package. I love this package. I have an X and an S and they both have the power lift gate. The ability to cool the seats is a bonus when you are traveling in very hot climates. You never know - you may have to travel through California or Arizona in the future. I always include this package when doing my future builds.
6. Battery. If you can afford it, yes, the 90D is the best - 294 EPA miles versus 259 for the 75D. I have an 85 S with 265 miles and it has come in handy in a couple of supercharger to supercharger trips. Having more range also means that your battery should charge quicker making your supercharger stops take less time.
7. Autopilot. When I am building my future builds, I do not choose any of these options as you can add them later. The other packages cannot be added later. The package you are leaning towards is a good one, however and you can save a thousand dollars by getting it upfront.
8. Service plans. Service plans are a waste of money. My S is out of warranty (except for the 8 year unlimited mile warranty) and I have had 0 issues outside of a drive train replaced under warranty.
9. Anything else I should consider? Get the 19" wheels (stock). If you want to upgrade, go after market. The 19" wheels ride better and do better with potholes. My business partner has 21" wheels and he has not been able to drive for the past couple of weeks as his tires will not hold air after hitting a major pothole.
You can PM me for the referral code - I would be ecstatic if you chose me!
