I have an existing Reservation/Order from 3 months ago. I called to change from White to Red. I know Red is $2000 so no issue there. They told me I would need to pay $3,000 more as the price of the car increased. So, $3K for price increase plus $2K for color. $5K to change to Red. Is there any way around this or is this just how Tesla works? Would seem like they should honor the price I was given since I'm only changing the color (again, no issue with the $2K color charge). Thanks!
