i have a 2002 Rav4 AWD automatic that gets HOERRIBLE gas mileage -- 17 city 20 highway. I love everything else about it, but leave it sitting most of the time (drive second car) because it SUCKS gas. Thinking about trading it. Dissappointed in Toyota advertising on window sticker 24/29 mpg. How can I trust Toyota again on what they advertise on the window?
