Yup, but the big difference to the C8 is that that is pretty much the final price- no myriad of choices and add ons like the C8.
The only, absolutely only good selling point in my mind is you can still get a manual transmission. But not good enough reason for me to trade in my C8
that "3 litre 6" is the legendary BMW B58 inline 6. One of the best engines on the market and the best 6 cylinder on the market. I have it in my BMW X5 and I paid way more than 72k
