It's not our fault you didn't properly research the product you bought... Tesla changes prices all the time, on a whim, often with zero hint or advanced notice (actually not just often, but pretty much all the time). My Model X just dropped in price, so what? I got the car I agreed to purchase at the price I agreed to purchase it at...
Cars depreciate in value, substantially, the moment you take delivery so quibbling over a small price change when your car already lost significant value simply from being delivered seems not only petty, but a complete waist of one's time and energy...
