Per AutoWeek, Ford is seriously contemplating adding a Mustang-based coupe to Lincoln's model lineup. I'm wondering whether it would be called the Mark IX, or whether the Mark designation would not be appropriate. Also, if it were to be more luxury than sport oriented, would it have the LS'independent rear suspension? And if they introduce a Mustang based Lincoln coupe, why not leverage the Mustang platform even further, with a Mercury sport sedan derivative? I know Lincoln currently has the LS, but I read that '06 or '07 may be the last model year for the LS.
