Similar to my own story. Model 3 res on day one, always liked the S but decided it was not worth the cost difference.
After a recent change in my commute I started to grow impatient for not having a car and decided ro visit the showroom to compare the 3 and the S.
After looking at both right next to each other, I realized that I really wanted an S. Talked to a sales advisor who offered to look for inventory cars matching what u was looking for, she found the exact same combination (color, interior, autopilot), except it was a model X.
Spent a day looking investigating and comparing the S and the X. Did a 24 hrs test drive of the X, ordered an X (not the inventory one because of MCU 2). Spent up to the last second of my order being confirmed thinking back of the X and the S.
Waiting on my X for the last month and a half, still holding unto my model 3 reservation in case I change my mind.
Truth is you can't go wrong with any Tesla
