Do they offer new sedans with decent legroom?

I have been test driving new and certified used cars all morning and can't find any that are adaquate. I test drove a 2009 Impala, 2005 Lesabre, 2008 Avalon, and the 2010 CTS. Every one of them I had the seat all the way back and I was basically driving from the back seat. Right now I drive a quad cab Dodge Ram, but I want a car so I don't have to spend $140 a week on gas. Anyone have any suggestions? I have a 20k cash, but I could always anything over 20k if that's what it takes to get a roomy car.
