– What vehicle for single parents?

Hello to Alle My Renault Clio BJ 99 takes me to the finazielle Ruin. I am a single parent of 2 children (both under 10), since August 00 working all day, before Hartz4. I manage everything with all day working and education and so on. I wanted to get out of Hartz, but the Clio does make me financially worried. I put 300€ on repairs in the last 3 weeks and now the next problem is: he has starting difficulties, starts when he wants to. I need a reliable vehicle because I pick up the children from the day mother in the evening I need another car Only which one? – Do not have any money except the possibly to pay the Clio – the safety is the most important for me! What buys woman like this? – Please tell me with which you would let your women and children drive with a good conscience!!! Thank you!!! ****** Additional info: so, to clarify this more clearly: I do not want to criticise my previous lifestyle but I am looking for A NEW, cheap – recommended car. The Clio is sold for no matter what and the necessary money for a new car I get from my parents. I will then pay this in installments with you. So, please again: Which car do you think is recommended? Cheap price range, for single parents with 900€ freely available money so reasonably affordable? With it it is about safety – not about the price!!! Thank you!
