wheel locks keep people from nicking your rims and leaving you on blocks. I'm not sure how someone can classify DVD headrests as only being appropriate in large SUV's, makes very little sense to me to confine entertainment only to big SUV's, you know people who own MKZ's have children too, and they might even take a roadtrip...

When it comes to how well they hold mess in, yes.
I still like OEM mats to some degree. If it was up to me, i'd keep WT mats for winter and carpeted mats for summer.

This seems like a good plan. The WT mats just don't look as nice as the carpet. I would only use the WT mats year round if I lived in a place that got a lot of rain. Otherwise, it seems appropriate to switch between the two sets of mats as the seasons change.
