I'm glad I did. Best car I've ever owned
Ye I felt the same too, almost feel the same still even now. Don't know about the MY but the 3 drives wonderfully well, engaging and exciting. At 8/10s I find it to be truly excellent. When I test drove the M3 I was driving my Boxster (981 2.7 base boooo) and at any normal speed the M3 seemed just as engaging and had immediate throttle response. Wonderful thing. If you go hard the Tesla falls apart though, you can bottom out the suspension easily, composure disappears, etc. But you can't push that hard on public roads, so it's pretty ideal for real-world use. Also very little stability over 120-130mph 😬 Let's put it this way though, I sold the Boxster a while after getting the Tesla because I literally never drove it. Even more telling after 2yrs I still don't miss it.
Software (in the infotainment) is great too, albeit Netflix and Disney+ on mine are becoming unusable due to lag and audio sync problems. The problem is Musk. Removing radar, USS, lumbar... Basically the car gets functionally worse via software updates now and for no reason. Why take a fully functional car that someone already owns and make it no better than a Renault Clio base model? The radar is even coming back in the future, so it's a total waste. Basically all the self-driving stuff is slowly ruining the car, bit by bit. The new cars dropping off the stalks? Who needs stalks when the car drives itself? Oh wait...
I think in the US it's a little different. I wouldn't be surprised if there are less phantom brakes and the auto high beam works better. But in the UK it's becoming farcical on my car. The other problem is support, which seems to be same in US and UK where it's not the greatest. I fully appreciate it's probably even worse for Polestar in the US. But in the UK you can just go to Volvo (not all dealerships), and they're closer to me than Tesla too.
There is no perfect car, or we'd all have it. We all have different priorities and requirements, and that can vary substantially by location.
I'll be very interested what you think in 2 years time. For me, if I could roll back the updates to the last one before they dropped radar from the software I'd be a happy bunny still. But you can't, so I think it's an unsafe deathtrap that I can't even use cruise control every time I want to.
