Fun fact: Alcantara is an Italian company brand name. They make simulated suede. Some users of Alcantara call it "Vegan leather." There is no animal components in Alcantara. It's all plant and chemical components.
I for one don't care for it in the Challenger. The Alcantara seats in my 392 really cramped my back/legs (I'm 6'5"). The Laguna has extra bolstering and padding and I don't get uncomfortable at all in it. The Alcantara really isn't to blame though, it's the difference in seat design that affects me. My gripe on Alcantara is that it is near impossible to get greasy stains out. I had a stain on my passenger seat cushion that I, nor a professional upholstery cleaner could get out. I have no idea what it was.
