Personally, when I was riding in the back of my boss's A6 (RS Avant, the V10 version), I didn't find the car that comfortable. Certainly not for the price (though he apparently bought 2nd-hand, having someone else swallow the 30-50% deprecation). Sitting in the driver-seat is something different, of course. But I sat in the back as a kid long enough...
To each his own, of course.
But even though I drive very little and could probably get by with a 10000km/year lease, it would still drive me nuts to have this limit nagging me in the back of my head.
That, and the fact that I would basically "rent" the car would totally take the fun out of owning it.
I get that with leasing a new car, you just don't have to think about a lot of problems that come with owning a car for fifteen years (like my current one). Rust, gearbox-problems etc.pp...
But while my bills from the yearly service are higher, my deprecation is zero. So I believe to still come out ahead ;-)
Maybe once the car drives itself and I can read a newspaper while it carries me to my destination, I will enjoy driving a bit more.
Until then, a commute by car (that I have to drive) is my worst nightmare. Regardless of the size of the car and the distance.
And because of that, I would try to spend as little money on it as possible.
From your initial list, I would probably try the E-Class.
If you check mobile.de, you should get a wider selection of cars. Especially, if 4x4 isn't required.
