Hello - I currently drive a Saturn Vue that averages about $65-70 a week in gas costs. However, the note on it is $250 a month. I am looking to trade in for a Prius (used) but am trying to compare the increase in the note vs the decrease of the gas costs and see if it's worth it. So I was wondering: 1) what is the average note on a basic model Prius (no bells or whistles), 2) what size is the gas tank? 3) how much to fill up at a cost of around $3.65/per gallon? 4) any negatives about the vehicle regarding handling; 5) what about space? the back looks to be about as big as my Vue maybe only a little smaller; so how does it compare with mid size SUV?

Thanks in advance! Can't wait to get some answers and opinions.
