Clearly it is all about profitability, If a car was ordered in Sept, has number 18k and is pushed up it is about the price tag. That may be a good business decision to make the first quarter profitable, but is leaves a pretty bad taste in my mouth. How may more will be inserted in front of me? and I didnt order a cheap car, its freaking $77k.
I understand you are frustrated but profitability is important for them at this point. We all want the company to be around in the future so our cars (regardless of model and options) can be maintained and serviced. This obviously didn't meet the expectations you had when you finalized but hopefully your wait isn't too much longer. You see the same story with Signature customers and the 'Sig tax', Signature customers coming off of the wait list getting their car after early production customers and 40 kWh customers who won't get their car until after you (some could be in the first 100 production reservations and if they opted for a 40 kWh pack they'll get their car much later than you will). This still sucks for you but it's an amazing car. There really is nothing you can do about it at this point as their production schedules are set but think you'll enjoy the car once it is here.
If they will allow you to upgrade to air suspension to get it sooner you might consider doing that if they wait is worse than the increased cost. They might not let you change since you've finalized of course though.
