2007 Mercedes-Benz CLS-Class CLS550 4dr Sedan (5.5L 8cyl 7A)
The CLS550 has both more power AND more room than I expected. An absolute BLAST to drive and the back seat is more spacious than it looks. It has a low roof line but it opens up once you get in the back seat. The front is totally spacious. Handles much better than the BMW 545, 550 and 750. I have owned a 750i and it was too big and made me feel old. The CLS turns heads and puts you in the back of the seat when you hit the pedal.
The power, handling and looks. Plus FREE satellite radio. Voice command is also a very cool feature and more user friendly than the BMWs.
Like ALL German cars, the navs have gotten better in the last few years but are still not as good as the Japanese. Still, I wouldn't buy a Japanese car just for it's nav. I use the nav feature about 1 time every 6 months anyway.
