I had a chance to transport a few 2014 ATSes back and forth from various locations. The first time I drove one I was grinning so much I could have played the Joker in the next Batman movie and the amount of rubber missing from the tires was not insignificant. One of the salespeople - an older gentleman - walked up and asked me "Isn't that the worst car you've ever driven?" I asked why he thought that and he pointed out the hard seats and touch controls on the center console. He said he liked the seats in the Buick LaCrosse better and that Cadillac had lost its way. While I'll give him the touch controls, the hard seats had me laughing.
Yes, the LaCrosse has more comfortable seats than the ATS, but I wouldn't call the ATS's seats uncomfortable. They're firm, especially the seat bolstering, which is what you'd need on a track or for canyon carving. Neither of those are old man activities. I responded to him with a question "Have you ever heard of those high frequency noise makers that they put outside of some stores at the mall? Teenagers can hear the noise but we adults can't. They're there to keep away the riff raff. These seats are the same way, except it works only on the elderly. If you want a large, slow, comfortable car to carry yourself and your wife to Costco and the Cracker Barrel, then I suggest you buy a Buick. Cadillac is a young man's brand."
