Last year I displayed my Model X at a local energy fair. I had some issues with parents not controlling their kids (standing on the seats to jump into he back, or getting face paint on the seat backs. When I asked the parents to please be careful as this was a privately owned vehicle, and I was the owner, they were all surprised they were private vehicles and not dealer owned. They tended to quickly admonish their kids and move on. Interesting that they somewhat deemed it acceptable to let them run free for a dealer vehicle.
Several others asked why I was displaying my personnel vehicle - I simply stated that i felt it was the future of vehicles, and people should know what is currently available.
For this years events (2) I am preparing a placard to put on the dash that states it is a "Privately owned vehicle, and please be...considerate" - I am also making a folding poster board with the basic information I found myself answering time and again.
Many asked about the price....I have most of the options on mine (minus the sound/Stereo and wheel upgrades). I think this year I will simply state the base price (not quite so much...sticker shock).
I also put the car into Valet Mode to put small items from the cubby out of harms reach.
I have the 6 seat configuration - rear most seats are typically down - two car seats in the mid seats for the grand-kids (Which is why I ended up with a MX in the first place - but that is another story). I think for this years shows I will leave the car seats in, and one of the rearmost seats up to show the seating arrangement.
Have to read up on how to shut the AC off to keep the battery from running down -
Also remember bring a Lawn Chair and Umbrella (I stay with the car to leave it open, answer questions, and watch over the car.)
