Just that we all have different expectations of what sort of vehicle makes sense.

You are making a valid point that while it may weigh 5000 lbs, the X5 doesn't hold very much.

I made the point that whatever the capacity limitations, many of us have done quite well with far smaller vehicles, including going camping for several weeks with four people.

I think that the days of buying a 5000 lb vehicle to carry a very small family may be numbered. I am not sure what the gas price has to be to start to change buying behaviours.
