If you appreciate European (esp. German) cars and want more than what a Japanese luxury car can deliver, then you will love the BMW 540i series (E39). It has more than enough power to get the job done on the highway. Super comfortable on long drives. The Navigation system is one of the best. Perfect mix of Sport (w/ the sport package) and luxury in a medium sized sedan. At this price point, nothing matches it.
1) Cosmetic Looks. The E39 are classy looking compared to the new Bangelized E60's.
1) Steering is a bit slow in the 540iA. Needs faster ratio.2) A/T does not always find the "perfect" gear.
