That's why it looks smaller because it is :-) might keep ot level for storing things on it, another thing you didn't think about is where am I going to put the 10 cd player thing in the boot:-)
I was going to try and fit them from the boot and have the box behind the seats, but you would have to take out the spare tyre each time and a lot more work with carpets in the car
That's the same sort of thing I used works well, I wouldn't bother with the boot option I tried it and you would have to take the spare wheel out each time
