2005 Scion Xa, 59,000 miles for $7,800 or 2007 Toyota Yaris, 79,000 miles for roughly $8,500??? HELP!?

I am deciding between these two cars and am torn between the two! I love the Toyota Yaris looks (4 door sedan) with the rounded front and good gas milage also! But the Xa is also very nice looking and has great gas milage! Money is also a major factor..both are a little over the price range but if i know it's a good deal than i would be fine
