Purchase advice Punto Diesel as commuter vehicle

Hi, I’m looking for a cheap second car. So far I’ve made my way towards Corsa, Clio, Peugeot 206 smart. You don’t get around the Punto as 188 JTD when searching. So my question: How durable are the boxes compared to the other brands. – 100km a day commuting distance – workshop costs? – Maintenance? I mean the years of construction from 2000, rather 2002 to 2007 (about 4000€ purchase price) depending on the km stand. What can you recommend me, or even advise against Fiat diesels?
