Just purchased a Model 3. After getting home, I found a Monroney sticker in the car that's lower than the one I was given prior to purchase by about $4500. This was a demo, so it's a few months old. Dealer says the MSRP must have changed after they got the car. Anyone else run into this? Never had this happen before and I know Tesla operates a little different than regular dealerships, so not sure if this is unusual?
