2007 BMW X5 - Owners? - Impressions?

The X5's have been pretty good with reliability up here but most people who buy one go through brakes like no tomorrow because they use the same stopping distance as their previous car and this thing is heavy. The mileage is somewhat poor from my point of view but I drove it like a race car and didn't put too many highway miles on it, so my mileage was horrible. I had the 4.4 and a friend had the 4.8 and he went through even more gas. BTW The 3.0 isn't much cheaper on gas unless you are very easy with the gas pedal. I truly believe the X5 is too heavy for the 3.0 to push it around, it seems to always work over time {more fuel} and the 4.4 seemed to be relaxed all the time. In the snow it was great and in the dry racing around corners it's very "safe" when it comes to body roll. You can really feel it lean but never did I think I was even close to lifting a wheel. Also they're "over built", they have a very strong, heavey duty suspension. {I haven't driven the 2007 model yet}
