Durability Fiat Punto 1.3 Jtd?

Hi everybody, I’m looking for a cheaper car at the moment and would very much like a diesel. Had a Polo 1.4 Tdi in mind so far, which I would get for about 4-5000€. Today I drove by chance a Punto 1.3 Jtd with 75hp and found the pull and the driving behavior really hammer good. Since I don’t know myself so well at Fiat unfortunately and you often hear about Italodreck, rusts anyway and engine damage, I wanted to make myself here now just make myself smart. Does this mean the durability of the engine and the technology. Is it to be lost with that of a polo? Would I be very pleased with an answer. Greeting Flex
