So after almost a year of waiting (and a lot of posting and reading here!), I finally have my car. Aside from the "glitches" (I have the buffeting issue, the loud vibration/hum when the A/C is maxed out, and the weird noise under full acceleration, plus the voice commands don't seem to understand me despite having unaccented Midwestern English!), the car is amazing. I have the 60kwh, and even though I drove the 85P last weekend, I am not disappointed. I can't tell the difference against the 85 at all, and the car is definitely wicked fast at all reasonable speeds. Handling with the 19s is a bit of a letdown versus the 21s, but my wallet thanks me for the long term savings!
Perhaps the best thing I can say about the car comes from my wife, not me. After many months of humoring me for something she clearly viewed as my car that I would be "forcing" her to drive to save son gas (I mostly just drive to/from the airport), she drove it for the first time and her first reaction was "Oh wow...my heart is racing!" After the next stoplight followed by a freeway entrance, she apologized for doubting the awesomeness of the car and said she had never understood before yesterday why anyone enjoyed driving.
But today was the most revealing of all. Her mother was at the same shopping center as us, and while I was in Best Buy my wife was waiting in the car. When I looked at the app to make sure the air had stayed on, I saw that she had called her mom to show off the car and was flying down a deserted road at 60 mph (and how cool that I could see that!!). Se was disappointed to bring the car back. Previously her only requests regarding cars were about color and interior space. Now she wants a Model X!
I think it is a great testament to the car that she loves it. My 6 year old literally guards it from the neighbor kids, and my 10 year old goes through the full orientation with them. It has instantly become a source of family pride and is being treated like a new family member!
