A new Tesla fan here and was not able to find an answer to my question on the Model S or X forums. When I placed a preorder for Model 3 I was probably around spot 350,000. I purposely waited so it would give more time to save up more money and also time for possible new upgrades and features to come out. I expect the soonest I could possibly get the opportunity configure my Model 3 is 2019 and possibly not until 2020. Lets just suppose that is Tesla is able to ramp up product much quicker than expected and sent me an email to request me to configure my Model 3 sooner than I expected. If I am not ready to order the car yet can I just wait and not do anything until I am ready to order? Based upon past history what have they allowed customers to do on Model S and Model X preorder reservations? Did they force users to order their car within X amount of time? If so, did they lose their spot in line if they did not order their car in time?
