Um...

Stern haven't included toppers with other LEs, so I can understand that Stern selling it separately and making it accessible to all.  If the topper was provided with the LE, Stern probably shouldn't sell it separately.

But the side armour should have been part of the LE package, and limited to the LEs.  LEs needed something more to justify the price difference to a Premium.  The side armour may have been enough to keep LE buyers happy.
