Help me to buy a new car :))

Good evening...

Today I invite everyone to a gesture of charity.

I present the problem:

My car has reached the end of life.
I was thinking of asking the community, not having sufficient funds, the help needed to buy a new car (second hand, new for me).

I looked at the market, the various models and the prices there are to buy a good car ...
I have estimated that a good car between 120 thousand km and 160 thousand km from 2009-2011 has a value between 9000 € -13000 €.

Surely I do not start from scratch because my fund is 4000 € but not sufficient to buy a decent car ...

What can I say, I thank you in advance and I invite you to help ...

These would be the proposals I evaluated:
