Search car with automatic

Hello, I’m looking for a used car with automatic transmission that doesn’t roll away on the mountain, when driving on. As I’ve already read, the then converter would have to have automatic…I hope that’s right. It should be a 4-door, if possible with parking aid back and my budget is about 3000,00 Euro. I know that’s not very much but it should serve as a second car. I already had one in my eye (Peugeot 407 SW Premium, BJ. 2005) but there I have a lot of not exactly good of read…for repairs and stuff. I had already thought about Opel Meriva or Corsa…but they shouldn’t have a converter automatic??? I hope you can give me a few tips which car I can take into consideration which are not so vulnerable. First of all thanks for your suggestions! LG
