I don't think of any of those first - I think of the more commonly seen models first. A8 is the last Audi most people would think of (for me it's R8, A5, A4, TT).
Well duh. This would have been a good point to make 3 years ago. But Lincoln has not only announced plans for unique vehicles and upgraded dealership experiences they've taken actions - like hiring a team of over 100 people dedicated to turning Lincoln around and having a dedicated design staff (and killing Mercury - don't dismiss that commitment).
This is akin to a sports team saying "what we used to do isn't working so we're going in a new direction with a new coach and some new players" and having sports reporters say "this team will never go anywhere if they keep doing what they're doing."
By the way - if you take the MKZ concept and super-size it the new MKS, throw in a base 3.7L DI 330 hp engine with a 400 hp 3.5L ecoboost optional engine and standard AWD - why wouldn't that compete with the S class, LS and other full sized vehicles? Those aren't exactly canyon carvers - they're more about luxury appointments and size than handling.
