The 6.2's seem to be OK as long as they are maintained (just like MB!) but longevity wise don't expect 500K miles like a 300D. At 140k if it was maintained should be good for another 100k easy. As the orhers said - stay away from the Olds 350ci diesels that were simply converted gassers, but I don't think it was ever used in a Suburban.
