Well, first off, you're wrong regarding my use of the M3's performance features. I did European delivery, and did 900+ miles of Autobahn driving in the car, most of which was spent cruising at 140 mph+, including three or four runs up to 165 mph+. Also, when I had the chance, I would take it to the mountains of North Georgia/Western North Carolina to push the car to my limits. Having both done multi-day performance driving schools with BMW's own driving instructors up in Spartanburg, SC, as well as having done hot laps with those same instructors on the Daytona road course, I know the car is capable of performing beyond my own limits, but I am capable of pushing it to about 9/10ths on a track and 8/10ths on a suitable mountain road.

So yeah, I used the performance features of the M3 on many occasions.

That being said, I live in Florida, and the car was, frankly, boring to drive on Florida roads. Driving fast in a straight line at speeds that won't result in my arrest aren't a stretch for the car, and driving the car at my limits makes me a threat to the safety of other people sharing the road with me when I find corners. There is a sweeping right hander on the Interstate off ramp near my house that I could take at 110 mph without the car, or me, breaking a sweat.

Moving on...

You might be right that renting a car once a month is a hassle for people. But I don't think most people go on 100+ mile drives every month (or at least average one trip like that each month).

And I always love how people talk about how much better it is for the environment it is to buy a used car rather than a new car, as if used cars just appear out of the ether. The people who buy my off-lease cars share in the carbon footprint of producing the car.

And even ignoring that, the lifetime carbon footprint of an EV, PHEV, or even just a non-plugin HEV is going to be lower than that of a ICE-only equivalent vehicle.
