Hi all, So I ordered a 60D Model S on 10 April before the 60 KWH cutoff, delivery scheduled for 21 July due to my moving situation (currently live in Alaska, Permanent Change of Station move to east coast). Tesla is now telling me that they won't have parts available for the 60D with solid roof, so they are upgrading me to the 75D with glass roof, but that I have to pay the $1500 charge for upgrade. Super frustrating since I do not need the 75 KWH pack (hence why I ordered the 60). I don't see legally how they can make me pay for an option I don't want or need just because they don't have parts on hand to make the smaller one. The terms and conditions of the sales agreement state: "The Vehicle Configuration describes the vehicle that you configured and ordered, including pricing." Also in the terms and conditions: "Your Vehicle is priced and configured based on features and options available at the time of order. Options or features released after you place your order may not be included in your Vehicle." This tells me that Tesla has a right to sell me the 60D or can choose to upgrade to the 75D, but at original price. Anyone in this boat or have any advice? I'm currently working with the DS, but escalating to his manager. Thanks for any feedback.
