Personally, I'm not sure it matters, everyone knows that Lincoln shares platforms with Fords.
The key is to get some interesting product out there, soon, before people drift away completely. The MKZ looks promising.
One tidbit is hopeful: From Paul Eisenstein: "Rear-wheel-drive is definitely in the works," one of Ford's top executives confirmed in a background conversation with TheDetroitBureau.com.
Let's hope so! Based on the lack of rear wheel drive platforms at Ford (you have Mustang and Falcon in Australia) I am guessing they are looking at the obvious and resurrecting the Lincoln Coupe, based on Mustang. Will they call it the MK9?
