I just did some research on the official benz site and I see that sedan E class has the highest mpg rating.. It is listed has 15-17 city and 23-24 on high way. The price is in middle range for this model.. If you want to save money on gas, I really do not recommend you to buy suv cars from benz since their mpg rating is really low.. Since you drive far away for your workplace, I think you should go with the E class since its highway mpg is really high.. I think there was this one youtube video that teaches you how to save gas by tuning your car.. I am not pretty sure what the title of the video was but you might want to find a video that teaches you how to tune your car to save gas.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
