"customers will need data access within their vehicles. They can either purchase a data plan from a provider or use their smartphone's existing plan via tethering." - in other words, to gain the privilege of saying 'Hey Mercedes, play Apple Music', they must pony up for a new monthly cellular fee or wire their phone to the car.  Yet if they do the latter, they'd have access to Apple Music (and lots of other features) anyway via CarPlay.

it is not for A or B series. Is for S or C. Makes sense 

For what is worth: I have (mild) asthma and some lung issues. Measured watch O2 against pro grade medical equipment twice. 

- measurement error is below 1% (when done right)
- one “fake” reading (around 89) during an spirometry. Re-did it. In line with medical equipment

My take is that if you (more or less) know how your breath is going, the measurement is good enough as to not justify buying a separate device. And yes, sometimes you waste time measuring  and the measure can be wrong once in a while.  

Just my 2c

I have upgraded my Stainless Steel Apple Watch every year since the first Apple Watch 0 ... except this year.  I get the stainless steel because it can be polished and can continue to look band new through its lifetime.  I always hand my watches down to family or spouse... someone always needs an upgrade; so I never feel like I am wasting $$ upgrading yearly if someone else continues to use it.  I did have a 6 on order, but for me the big feature would have been the SpO2 sensor.  However, when I heard numerous reviews that the Blood Oxygen Sensor was so un-reliable, and had to be sitting on your wrist "just right" to get an accurate reading I cancelled my order.  I was hoping your review would touch on this, as there are very few 6 month followup reviews like this.  I've had no issues with my 5, so I don't regret skipping the 6 at all.  I haven't heard anything about WatchOS updates improving the accuracy, so I guess I'll wait and see what the 7 has to offer.
