I'm tossing up about getting hatch or wagon, I think I'll probably need wagon but finding it had to find length of boot with seat folded down.  Can anyone help me, I've seen other posts with measurements on images, but I can't open the images. 
I'm wanting to buy secondhand but want android auto, I understand in Australia that android auto was introduced in the hatch from MY16, is this correct?  Is it the same for the wagon?  Thanks
