I have a 06 Dodge Magnum and I get 20mpg when I am on the highway or driving around town. I also have a boat and utility trialer as well and I use it to haul them. When I am pulling a trailer mu MPG drops to 10 or 12 but I don't pull them that far. I save enough money on gas that is pays half of my car payment. I down sized from 02 F150 Supercrew 4X4 and I was only getting 10 to 12 mpg with it.
So I got that going for me. Which is nice.
