Man y'all complaining about 13-16 mpg?? When I drove my old '87 Chevy with the 350 it would make 8 on the highway. Talk about I was excited to see my '02 Chevy get double digits (10mpg)!!! Now my '08 Chevy averages 13.5 city and I couldn't be happier. If you want fuel mileage buy a Prius.
Although when my buddy pulled my boat with his Eco-Boost it made almost 15. I was really impressed with it.
