i thought the endura engine was pretty good.as people have said u can run them into the ground,solid as old boots.i guess due to people having issues will most things they will say it was terrible engine.the psa 1400 diesel may not set the world alight but it will regularly return 50ish mpg even on high mileage ones.the 1600 psa engine is used in several companies,ford/volvo/peugeot/citroen and even the diesel minis i believe use it

cant think of a really bad engine i guess early engines v4/v6
