I just sold my 3 and bought a new S (after a 5 month long order-to-delivery wait).
Last 20 years of car history: BMW 3-series, Miata MX-5, BMW 5-series, Porsche 911, then in 2018 a Tesla Model 3 LR, and now a 2022 Model S LR.
As you can see, I like two kinds of cars: smaller+tossable, and larger comfy+sporty. I appreciate both, but as I've approached my fifth decade, I'm definitely leaning toward the larger sedans. Part of it is practicality with a family, part is getting a bit older and appreciating creature comforts. Showing up at work reasonably fresh, despite a long SF Bay Area commute, is worth a lot. ...Even though many of us are not commuting much these days -- on the days we do, it's really great.
Specifically what I love about the S over the 3:
- comfier ride / air suspension is *far* easier on my back
- quieter, which translates to a whole lot less fatigue
- bit more range is nice, but mostly a wash for my daily usage pattern (I went from a Tesla-rated 303 to 375)
- more space, comfier for wifey and kiddos, guests, etc.
I originally wanted a Model S back in 2018, but I hated the idea of buying "old tech", and I liked the minimalist interior of the 3 far better. Glad that Tesla finally refreshed the S. Additionally, I find the Model S sufficiently fast and powerful -- more than I can legitimately use. But the M3 definitely
feels faster, and is much more nimble. The M3 is fun. But the MS is where I want to be.
If I had unlimited funds, I think the ideal pair of Teslas is (1) MS for the daily, and (2) the Roadster for the weekend, in a few years.
If you can only have one, the M3 is a good compromise, but it won't be truly great for any day of the week.
