That car is bananas, so fun to drive. I had the 2013 e92 m3 competition but very similar. Incredible luxury, 3.9 second 0-60 that literally slammed your head back into the seat producing a stupidly happy grin.
The best part of that car was the handling/suspension and the stereo though. You could put it in M Dynamic Mode, which let you do controlled drifts. Shredded tires, but goodness it was fun to drift corners everywhere.
The sound system was the best I've ever heard, far better than a custom $4,000 system. 800 watts, a 10 inch sub under both front seats. That car was the closest thing to perfection I've personally ever driven. Its only real flaw was it didn't have quite enough low end torque ( 300 lb ft ) because it was a naturally aspirated v8. Plus you had to really baby the throttle on the low end so the tires wouldn't start sliding around when you accelerated from a stop.
I had literally 0 problems with it in three years outside of the stupid Takata airbag recall, which is why I didn't keep it. But you can't blame that on bmw. Plus I mean I spent a lot on tires, but that's on me :-)
At the time I test drove a comparable tesla and thought it accelerated really slow and had poor handling. Also it didn't even have a backup camera, decent stereo, or integration with popular music streaming services. But I hear they have gotten better.
For me the big benefit of the tesla is that you can shave 15-20 minutes off your commute by using the carpool lane and still have a decent car. Plus you are doing something to offset climate change.
