Because it's not all speculation.
It's a FACT that they killed Mercury and sold the other PAG brands.
It's a FACT that they are utilizing unique sheetmetal, interiors and features like electronically controlled suspensions and retractable glass roofs.
It's a FACT that they are changing the dealership experience.
It's a FACT that they now have a dedicated staff of 150+ people who work on nothing but Lincoln including 100% of the vehicle design.
Gloria is right. Even if the MKZ turns out great, you'll say that's just one vehicle and it still doesn't have a unique powertrain because the 3.7L is available in other vehicles.
If Lincoln doesn't build what YOU want it to build they're a failure. We get it. Move on.
