Iknow how you feel , as to wanting to improve your cars performance. I too have a 300e and I know that car is a dog. Well its overall a nice car though. The only thing is that i hate being blown off the line by ford Taures's and even minivans. People make fun of my car. Indeed it should be faster with a 3.0 engine. Its pathetic that such cheaper cars are faster. Well I guess when I graduate college I'll get a E55
