Really good to be aware of this kind of marketing, thanks for posting it.
I have fallen for this with the GM parts for my GMC Safari Van just because I didn't know there was 3 different levels.
I always use Motorcraft on my SMB. But if you are buying your parts from Amazon, ebay or some other online store looking for a lower price on Motorcraft parts, be aware of counterfeit parts as well. Saw this video explaining how sophisticated this counterfeit stuff can be.

Makes it harder than it should be to do a job right.
