Honda Accord Coupe v Dodge Challenger

Will 5 more mpg really make much of a difference?

I'm planning on buying a new car in a year or thereabouts and I am looking very closely at the Honda Accord coupe 2008, and the 2009 Dodge Challenger SE. And I like both cars.

The Honda Accord gets 30 mpg on the highway while the Dodge Challenger only gets 25 mpg.

Is that five mpg difference going to be a significant difference, or are both cars pretty much the same in terms of their mileage?

Thanks.
