I'm curious if anyone here has made a change to their vehicle after the order was confirmed. My order was confirmed 3/16 and still awaiting production. I do have a VIN # already. I know its $500 per change but I am worried that if I make a change, it will bump be back in terms of production schedules. If I did make changes it would be to delete the full self driving option I paid for and go with stock wheels. (I purchased the 21" Twin Turbines and I think I want to do aftermarket wheels). Basically shaving $7,500 off the price. Any info on this would be appreciated!
