I think I paid about £120 to get electric in the back a couple of years ago. Like said above, there'd be nothing stopping the kids in the back messing about with the manual ones. It's also amazing that a car with these kind of list prices doesn't come with them as standard. Embarrassing really.
It is very strange - it's not a budget car so you would expect the electric windows really, especially in the higher trim levels like the FR.
