Rear wheel bearings on the cars with rear disk brakes, they have ventilation issues which over heats the bearings causing them to fail. You hardly see rear wheel bearing failure on a drum brake car.
Head gaskets on the 2.5 SOHC every 70K ish, some exceptions.
Head gaskets on 2.2 SOHC, 1.8 SOHC not so common
Head gaskets on 2.5 DOHC not so common, more common higher mileage 150K plus
Harder to do HG's on DOHC due to removing the cams to get the head bolts out.

PLUS, I have the car you want if she needs an auto
