In this video I get into a question I’ve been thinking about a lot: does it actually make sense to sell a brand-new 2025 Model Y and jump back into an older 2017 Model X P100D just because it has free Supercharging? On paper, free charging sounds like the ultimate hack, and the P100D is still a monster. But I break down the real-world stuff that matters when you live with these cars every day—cost to own, what you gain, what you give up, and what ends up being the deal-breaker. I compare the day-to-day experience between the “old flagship” Model X and the “new workhorse” Model Y, and I talk through how things like software, features, reliability risk, and overall value play into the decision. The big takeaway is that free Supercharging alone isn’t enough to automatically make the older X the smarter move. There’s a clear winner depending on what you care about most, and I lay out the logic so you can apply it to your own situation before you make an expensive switch you might regret.
