I placed an order the end of July for the 90D. However, after the first manufacturing run, I was informed the car was so defective, that they had to start anew. Finally it is here for pickup next week. I have two concerns: Do buyers need to be concerned that there may be a manufacturing problem in general or perhaps this was just a rare event? Although Tesla was kind enough to provide a non-Tesla loaner for the last two weeks since I sold my car in anticipation, do you think I should ask for further compensation, such as an accessory?
