After a 15 year hiatus, the Continental was reintroduced for 2017.
Lincoln allows borrowing the innermost lower anchors belonging to the side seats in order to install a car seat in the center – however, the spacing between these anchors is 18.1 inches (standard spacing is 11 inches). Learn more about center LATCH here – as it depends on which car seat you have whether you are allowed to use anchors that are wider than 11 inches apart. However, due to the rigid buckles for all 3 seats, the extreme narrowness of the center seat, and the head restraint in the center that protrudes extremely far forward, it seems unlikely that any car seat or booster will fit in the center seat.
Tether anchors were factory installed for all 3 seats starting in 2000 (1995-1999 had them factory installed in the center, but not for the side seats). There are no head restraints for any of the seats. There is a shoulder belt in 2C. There are no lower anchors. 
The back seat of the 1995-1999 Continental looked the same as it did for 2000-2002. There are no head restraints for any of the seats. There is a shoulder belt in 2C. Tether anchors can be retrofitted for 2D & 2P. There is a tether anchor factory installed in 2C.
