Wanted: small car with large boot!

I currently own Hyundai i10, one of the things I really like about it is if you fold the back seats down you get a completely level boot space which holds tons of stuff. My car is now coming up for 7 years old and I'm looking to replace it but in the new i10 the rear seats don't fold completely flat. I've looked at lots of other small cars but they all seem to have the same problem. Can anyone suggest a car that has a flat boot space when the rear seats are down...a CD player would be a bonus!
