I have decided to lease the X. I now need to educate myself on leasing a car. Does Tesla negotiate on it or is it a take it or leave it choice? I've seen through the forums talk of residual value and I think money factor. If there is a thread that talks about leasing please point me to it (I have seen a good one before, but I can't find it when I need it). I was told by my DS that leasing the car does include GAP insurance so at least you don't have to worry if you will owe money if the car gets totaled.
