Our last 5er, an '06 Titanium, had a nice molded rear cap. The current one doesn't. We also looked at others from low end right up to way off our budget scale. There was a, best guess, 85% no molded cap vs a 15% with. I asked the dealer and his answer was simple, money. We will order you one with a rear molded version for several thousand dollars more or you can purchase what we normally stock at a much better price.
I really liked that molded rear cap but not that much for lots more $$
