I’ve used indrive 7 for 11 months and I drive 8 for 4 months. It’s not much of a difference for me, I prefer Apple car play to be used mostly anyways…
The climate control buttons actually were not sensitive enough in my 3 series it was annoying, where as the touch screen for idrjve 8 works every time. The app for my 3 series sucked as well for pre conditioning, like worked half of the time. It works every time with the I drive 8.
I do miss having a gear shifter though, my i4 just as that switch.
It’s very quiet. It feels similar to a 3 series, but not quite the same. I think it’s due to being a heavier vehicle and 6 inches longer than the 3.
I do miss my previous car sometimes, but this one is significantly cheaper to own.
