The last Cougar was not based on the Probe. It was Ford's last "World Car" in the Alex Trotman era: designed in Europe, based on the Mondeo, and intended to replace the Probe in North America and sort of revive the Capri in Europe. Deemed to be an old man's car in North America and too American in Europe, it failed in both markets miserably.
As for the Marauder, it IS an old man's car. And it'd be just the same for the Cougar if Ford revived it yet again as a Mustang clone: an old man's Mustang.
