Here is my post from another thread, but I think is spot on for you!
My $.02 sense for you is that you need to decide what you are looking for at the root of it. I went from a last gen Manual Audi A4 and we had a M5 at the time as well. Nothing compared to that visceral 4.4TT in the tunnels. But honestly, the power was lacking in comparison to my P3D (mind you the MT had a Dinan tune with HP in the 600+ range). The feeling of lack of torque was due to having to deal with transmission hunting for gears, even with the quick gear changes of the M5. If you need the sound, you will be disappointed by the Tesla.
Here is my concise summary. This comes from driving my cars, company cars, and family cars a significant deal. Cars I have put enough mileage on to form a sold option in the last 3 or so years are (all 2013 or newer): MT Audi A4, Scion FRS, M5, Prius Prime, Genesis G80, Model S, P3D (my current DD), Volvo XC90.
Luxury: The M3 is less luxurious than competitors on the interior. This has nothing to do with it being minimalistic; that is it's most luxurious feature. All materials you touch feel great, but everything feels a step below the Germans. When I step into my 115k mile Audi, it still feels new and the interior is beautiful. I feel at the same age, the Tesla will be showing more age. There are also weird creature comforts missing compare to competitors (cooled seats, 360 camera, heated steering wheel, ext). The car is also noiser than I am used to on the highway. It is luxury quiet, just not Audi quiet. That being said, the white seats are beautiful. Overall, I would say it is definitely a luxury car, just not quite up to Germans, but still very well executed.
Sportiness: The handling of the car is amazing in my opinion. The stock tires are too narrow for the track, but that is an easy fix, and they are plenty for spirited driving on regular roads. It honestly feels as nibble as my old FRS, despite some major weight disadvantage.
Features: LOL. Nothing is close. It is amazing how my car gets better every day, I have never experienced anything like that. For any real highway driving, Autopilot is amazing. I arrive rested to places, it is a whole new look on driving. This car is so hard to compare to anything else.
Performance: Absolutely amazing. As I said, I have had some serious performance cars (from light and nimble to brute) and this is my favorite bar none. The instant throttle is amazing and changes how you drive. There is so much on tap. Over 70, it does lag a bit, but still plenty there! Also I feel the AWD setup I'd very underrated. There are two motors! You can do SOOOOO much more with that from a handling perspective. In the corners it is so balanced. You start to get a bit of oversteer, then bam, the front motor starts pulling you. It is such a weird, but amazing, feeling as it is so instant and direct.
Style: Meh. The Model S was stunning, and still is a beauty. The 3 is a very nice looking car, but is not trying to hard to be anything, it is just a sharp car. That being said, the P brakes and spoiler give it a nice stealth look. But you can do a lot to make it more aggressive. I did a blackout and new rims and it looks a world better!
Overall: In my opinion, this is the best car out there right now. It has its flaws, but they are beyond outweighed by pros. I believe I have a qualified opinion on sporty and luxury vehicles to form this opinion. The Alfa is amazing, I was looking at them; they are stunners. But man the 3 is just light-years ahead. While there are a few flaws (light on looks and luxury) the pros beyond outweigh that. You have to also realize the pros are not something you are used to comparing (Autopilot, updates, instant acceleration, dial motors) and once you have them, cannot go back.
Just my $.02!
