I have driven a 2004 saturn Vue and a 2007 Honda Civic. I am use to these type of cars they are bigger then some but not huge. I have noticed that the Hummer H3 isn`t much bigger.then the 2004 saturn Vue and a 2007 Honda Civic. How different is driving a Hummer H3 compared to 2004 saturn Vue and a 2007 Honda Civic?
