FULL MERCEDES E550 ARTICLE @ INSIDELINE.COM: http://www.edmunds.com/insideline/do/Drives/FullTests/articleId=147866?tid=edmunds.il.home.photopanel..1.* Here's the biggest difference between the 2010 Mercedes-Benz E550 and the 2009 Mercedes-Benz E550: The 2010 costs $5,400 less. Usually, we save money matters for the end of a Mercedes E-Class road test. First we tell you that it has a perfectly relaxing ride quality and a smooth V8 with an indiscreet amount of torque. Then we describe a down-to-business cabin dominated by leather, wood and COMAND. Finally, though, we have to talk about money, and, well, Benz has a well-earned reputation for pricing its sedans higher than everybody else. But this time it's different. When the 2010 Mercedes-Benz E550 goes on sale in June, its $57,175 base price will land it smack in the middle of the V8 midsize luxury sedan class. It's also cheaper than anything else coming out of Germany.
