I've always hated the Model S and hated the Model X even more when it came out. I didn't like the giant portrait screen, the UI, the seats had no support for spirited driving, the steering wheel was too big, the car was too big, too heavy, it drove like a boat around corners, interior ergonomics were horrendous (e.g. cupholders, storage, bins, etc). I loved what Tesla was doing, but I hated it's first two mass-market vehicles. Felt very much like a first-generation product, which it was... Sorry not sorry.
Based on that, I didn't expect to love the Model 3 as much as I do now. It is refreshing, great interior design, love the single landscape screen, interior ergonomics is much better with gobs of storage, smaller car, smaller steering wheel, quicker steering, handles well, remains relatively flat through corners, much lighter. It's a second-generation product, and definitely feels like one too.
Are there downsides? Yes. Small trunk opening with manual tailgate and smaller cargo capacity. That's pretty much it. I think the 3 is more comfortable than an S, handles better, easier to drive, easier to park, etc. etc. etc.
That being said, these are just my opinions and as someone in my 30s with no children, I clearly prioritize certain features more than others. Unashamedly so! Like others mentioned above, I'm one who prefers the BMW M3 over the 5 series and 7 series. Probably even prefer the BMW M3 over the BMW M5. Actually, I would totally get the new M2 Competition over the M3/M4/M5/M6/M8 (but maybe not for the same price). My priorities are just different.
If you prefer the base S75D, then why pay MORE* for a loaded P3D+? Just get the S75D.
As for me, I would be asking myself why pay for a base S75D with less range when I could get a loaded P3D+ with more range for the SAME PRICE**?
I chose to save a huge chunk of cash and just get the 3LR. At least that's what I told myself to feel better when I test drove the P3D...
For the sake of argument and because I can:
