Remember that most luxury car buyers don't do their own maintenance so they'll be visiting at least every 6 months or so. And that's one of the big appeals to luxury buyers IMO - a cushy service experience.
You can debate styling all day long. There is no right or wrong answer - there are buyers for all types of styling if its done well.
Lincoln will not be a cushy ride with no power or handling. OTOH there probably won't be a barn burner M/AMG/CTS-V top end model right away either. There is a sweet spot (IMO) for Lincoln with elegant styling, modern unique features, excellent materials and dealership experience and above average power and handling with ecoboost engines and AWD and electronic ride control.
If that formula is applied to all 7 vehicles then Lincoln could easily make a run at the top selling luxury spot within a few years.
