Which Car would you choose for comfort - BMW/Merc/Audi

[brmeyers]

Hey Everyone,

I have been inactive here lately because I am searching diligently for a new car now.

I really want something comfortable for longer drives and luxurious in the $150,000 range. Not too sporty but luxurious. Comfortable not stiff.

I have my 911 for sport, and looking to trade my X5M because its just not comfortable at all for longer drives. Actually been disappointing because my previous X5M E70 was so comfortable. Can't believe the new F15 seats and ride is much less so.
And I am finding currently I have no need for an SUV.
So here I am looking for comfort for days I want to relax and not race, and long drives (especially).

Here are my top choices so far and all definitely would be fully loaded to brim minus unnecessary stuff like pedestrian night vision, etc.

1) 2017 BMW 750
2) 2017 Mercedes S550
3) 2017 Audi A8/S8
4) Other (in $150K range loaded)

Honestly they all look good to me, I am curious if anyone here has had 2 or more of these to compare long term for comfort, especially on longer drives.

I have my 911 GTS for adrenaline/speed, but ALSO really want something comfortable and luxurious for serotonin/peace.

Thanks for your feedback
