My average purchase price is $29.90 and now have enough to more than buy a fully optioned Model S, and perhaps an E in later years. I wandered into the White Plains dealership last August and announced, in typical bombastic fashion I could buy the car with the stock, but I wasn't a buyer. The salesman immediately responded, "keep the stock." Now the stock is my largest holding, but the entire portfolio is a good nest-egg but will have to get to a million or more before I would sell other stocks for a Tesla. I will be long until 990 at least!
