Im looking at Buying one of these cars . As far as im aware they both are pretty much the same car its just the engine that changes. I test drove a E330 coupe and I really liked it but I have a feeling the E550 is better. I am trading the porsche in on one to save some money and for alittle more room for my daughter. How are these cars ? Any problems /recalls. 2010 vs 2011 any difference. I want to stay under $41000 If anyone has any input I would greatly appreciate it . Thanks guys
