I have owned the 2005 X3 for about a month and I have truly enjoyed the comfort and solid performance. The 3 liter engine is responsive with 225 horsepower. The interior is very comfortable, even with 4 adults, but could use more storage space. Panoramic sunroof is great on the 2 trips I've taken with it. The automatic transmission has the ability to shift as a manual is a great feature when driving in the city. Overall very pleased.
