I would just produce the "base" model for the little while. Options (at no cost) for color (inside and outside), "nicely equipped", at $35k. Two wheel drive, 60-70kWh (whatever can get the range deemed practical.) If your $35k is a base model that nobody wants, and it's just there so that you can say that you've hit the target price, you lose on the mission. And enough people that would want the P and 100kWh and dual motor will still buy the "base" one, then upgrade a year or 18 months later, getting more people into the CPO cars...
