Correctomundo. My 02 Ford Explorer does anything I would want in an SUV. I actually don't NEED any other car with an S420 and a Ford Explorer. What I'd LIKE is to emulate the quality and impression value of my passenger vehicle, and have my 4 wheel drive in my passenger vehicle. Then I'd get rid of the Explorer, consolidate insurance coverage, and so on. I don't think the Subaru will work, as I want to use this for my "dress up" work car, although I think Subaru has proven itself better than anyone in the all wheel drive passenger vehicle department over the years, and you do get the most bang for the buck.
I think I'm down to the A-6 with the 4.2 liter engine, the Mercedes E 500 4 Matic as choices. The Audi appears to be wider, and seems to have more rear seat room, and a longer history in all wheel drive. Neither seem bulletproof in reliability, but I don't like the SUV platform, and I'm not seeing a sedan from the Japanese in a four wheel drive format, unless I missed something.
If I don't go with 4 wheel drive, then I can just keep my 99 S420. It does everything else I want. Although I do worry about reliability on my S Class as well, particularly since it is out of warranty.
