There are tradeoffs involved in any car design. Reading your initial post, I'm sure the S isn't for you and I think it makes sense for you to hold off.
"I like some level of performance, so long as I can get 0-60mph in less than 7secs, I'm happy." kind of says it all.
Leaving aside eco items, the strength's of the S are its power, beyond lightning fast throttle response, family car suitability and handling - especially for a large family sedan.
The S has a magnetic appeal to people who want a drivers car. Clearly, that's not you. That's not meant to be an indictment or negative judgement, btw. There are a lot of drivers out there who want some performance and a lot more comfort and luxury.
Given that, it's hard to argue with the statement that for the $$, you'd be happier picking a different car.
Good luck and check Tesla another time. The base Model 3 might be a better fit for you. Only time will tell.
