So just how much space is there in the Model Y? We have a Model S and some of the videos I've seen make it look like there's not that much more space than the S and most of the video comparison discussions are with regard to the Model 3, not the S. If that's the case, the Y we have ordered isn't going to be half as useful as we'd hoped and we should probably look for a used X. This car is to replace a BMW 530xi wagon which has been our road trip car. Has anybody measured the cargo volume with the rear seats up?
