Several years back I got a new VW Passat. After one 400mile trip, one way, the driving hurt my butt so badly I almost could not make it back home. Two weeks before had made the same trip in my Boxster without any problems. Thereafter, could not drive the Passat for longer than 5 minutes before it caused pain. Didn't matter how I adjusted the seat. Doc said it was causing nerve damage. VW bought the car back. I had only put 2000 miles on it.

While the nerves were irritated I drove every 4 door I could afford both new and used. The only 4 doors I could drive for longer than 10 minutes were the Volvo S40 and the BMW 3series with sport seats.

Found BMW 7 series has a seat option that gel is pumped back and forth between halves of the seat bottom. It is slow enough you don't notice, but fast enough that you still get good circulation to your legs. They were just a bit out of my price range.

Ended up getting the 3 series with sport seats. Since the Boxster was pain free I now have a 928GTS and Cayanne Turbo that are a pleasure to drive (pain free). If the 928 and Cayenne seats did not fit so well and not cause any problems I would be looking for one of those BMW 7 series very seriously.
