Replacing an E350 wagon is hard, since we still need cargo hauling space and enough back seat room for three teens. Although the X3 had better handling, we couldn't give up the cargo space, so the X5 is the solution for the next 3 years. Only wish I could turn off or stow the nav/radio screen. It's distracting, especially at night.
I purchased an x5 35d and after 600 miles the check engine light came on. Took it to the dealer and it was determined that it has a faulty sensor. But because it's a diesel they don't stock the part. It's been three days and still waiting.
