Is it normal that our Arona FR doesn't have a second carpet on the lower level of boot. In other words when I lift the adjustable boot floor to it's top position all that's underneath is the empty spare wheel well so putting anything under it just clatters around. All our previous cars had a carpet so if you took out the adjustable floor you still had a carpeted boot. It's very strange in my opinion... or has it gone missing on ours?
