I have a Signature Model S car that fits me like a glove. After 73,000 miles I still *love* to drive it - that's never happened past 10,000 miles with any other car I've owned. It did have its issues at first (including a rather spectacular failure of the battery pack contactors that resulted in a newly-refurbished pack), but Tesla has always done right to resolve the issues. The customer service I've received is nothing short of spectacular.
I think by April you'll be just fine. Things iterate very fast; for example, that "FWD sensors won't stay stuck to the body" problem that I had? They already have a new design they're using to eliminate that.
You may have a few things you have to deal with at the service center, but I have faith you'll get phenomenal service, you'll love the car.
Thanks for the assurance, the X will be my first six-figure car so I don't want to be disappointed
