Good review. We test drove a 545i before buying our X5 and I agree with your comments regarding the differences in road feel between the two. If BMW made a 545xi it might have been a closer call.

My impressions of the 545i:
- Lots of power.
- Phyically roomy but slightly cramped visually.
- Very quiet.
- Styling still take some getting use to, especially the lights.
- The self-centering turn signal drove me nuts.
