Well, it never breaks as in: it will always get you to where you need to go because the engine just keeps running. Broken driveshaft? Stick a vice grip on it and keep rolling... And they're easy to repair because there isn't a lot in them to begin with, so you have a lot of room to work. Running gear wears and needs fixing but the core is nigh on indestructible. Same with the VW diesels from that era, the 1.9 mechanical.
