Help!! Fiat Punto – Good choice???

I need a car as soon as possible and have now discovered a Fiat Punto (not the new model) occasion in my price range. Now, however, I am advised not to buy a Fiat from various sides. Reasons: 1. frequent oil loss 2. he rusts quickly 3. electronic problems etc… However, I also read again that this is not true. Can someone help me and give me any tips???
