They are so different...
They are so different, so it really depends on what you need. The CLK looks a hell of alot cooler, however, if you are the primary driver for more than 2 people you might think about the E55. However, don't buy the CLK55 thinking you are buying a sports car. It's a sports coupe but needs suspension work. Despite their 5.5. liter engines, both cars are a bit underwhelming stock.<p>
