As someone else mentioned, it will be more expensive to maintain from an "equipment" perspective. It has more [at the time] high-end features like the active seats. If those fail, I don't want to think about the cost. Maybe it's one of those things you'd just leave broken. That just screams money pit.

Frankly, I think the V10 engine is awesome and the last of its kind but the transmission choices both suck. The SMG just isn't that smooth and is known for being terribly unreliable. The 6MT was a carryover from the E39 M5 so the gearing is totally wrong (you fall out of the powerband when shifting).

Thanks 🤟
