The biggest advantage is Cadillac has shed the old man car image. I live near an Air Force and an Army base and I see quite a few Caddys being driven by young airman. The most common model I see is the CTS and I'm starting to see a few ATS's. To be honest I can't even remember seeing a Lincoln in the past month.
Lincoln was also just poorly ranked for retaining value. I really don't think they even have a dog in the fight.
