Greetings, I am a longtime Model 3 wannabe. Thinking I will take the plunge but am not going to be in a position to take a test drive until around December 3 and I would want to take delivery of a M3 LR no later than 12/31 for tax credit reasons. Two questions, if I order today (11/22) and later after I test drive it I cancel the order I believe all I risk is my $100 order fee, and I cannot order a similar one for a year. If I take delivery, and for example, it does not fit in my garage (yes, I have measured and it is going to be tight) or for any other reason I would need to return it inside the seven-day window. Does anyone have experience with the return and is it as hassle-free as it sounds? Next, I think the auto park would help be shoe-horn this into my garage on a straight-in parking basis. It looks to me that I would have to order Full Self Driving to get this. Am I understanding this correctly? Thanks!
