Rental/Lease cars seem to set the bottom prices - you can always seem to buy a 2 or 3 years old Enterprise car for $13k. So much resale seems to depend on this. The economy is so bad that many people are convinced that this is the best way to buy a car. If all you want is a box and 4 wheels, maybe. I think thats where the Fiesta buyers are - plus the Fiesta is cooler than most.
My buddy did that at the same time I bought my SEL - he got a 2008 Civic for $13k. He laughed a bit when I told him I bought a new Focus. OK, we'll see who keeps what longer. I chose a loaded car in black that was very advanced for its time ( picked my '12 up in June '11) and I will save in the long run as I don't have to replace the car for many years in the future.
