Besides being cheap, I just plain don't like many of the features of the higher trims. No to sun roofs, no to leather upholstery, no to rear radar. If I could add a la carte, there would be few things on my list. Ventilated seats (fabric of course), heated steering wheel, and possibly upgraded stereo. But those higher trims add weight, reduce headroom, or have luxury stuff I just find silly. I wouldn't have gotten the LX if I could have opted for the tech package in the FE!
But I don't begrudge those who want such stuff.
