I would give Audi a chance, particularly the A6.
I bought a 2001 A6 2.7T instead of the BMW specifically because I found the interior to be superior (the BMW used those giant plastic buttons that are the same material as the dash for example) The drive train to be superior in terms of equivalent price (I was in the $10K to 15K range) and I got a 6spd bi-turbo with awd, compared with a 5spd na v6 2wd.
Lastly the Audi's subtle lines and smooth curves gave a nice subtleness to a fantastic machine without screaming our I DRIVE A BMW LOOK AT ME!
Neither of these are cheap to fix btw. Replacing a thermostat...yes a THERMOSTAT in my audi required $300 and would not be considered easy for a do-it-yourself-er.
