I'm enjoying a 1 day trial that my local Tesla dealer gave me in trying to decide between a reserved Model 3 and the S. The S is most certainly an impressive car and I'm leaning towards it. However I do have two questions. First, I hear an interior rattle coming from the right front side of the car and I haven't yet identified its location. Are rattles common on the S or is this a rarity? The car is new and only has about 200 miles on it. In feeling around, the front dash piece that adjoins the lower right side of the center LCD display, appears to be a bit loose. The left side is snug. Second, it appears (unless I'm overlooking something) that the car does not receive or transmit text messages via an iPhone. If that's the case, is there any talk about introducing that feature in the future?
