What are my chances of car financing?

Servus, my training ends in August and will be taken over for a limited period of time. I will only be permanently in 1 year. I would like to get an Audi A4 or Skoda Superb if possible this year. However, since I have only saved 3000€, as well as only one car, which is between 4000 and 500€ worth, it will not be enough for a cash payment. The price of the cars is depending on the brand and model between 29 – 35tsd Euro. My colleague in training has a car for 15tsd at VW. No one had to vouch for them or anything else. Do the car dealerships have their own banks? How does that work? At the savings bank, they want to see an indefinite contract. What are my options? They will probably ask themselves why I don’t want to wait until I am taken over indefinitely. Well, I finally want to buy a nice car, which I would like to drive for many years. Thanks to the current policy everything becomes more expensive until you can buy nothing more. Better now than never. I would appreciate nice and helpful comments Greeting Lukas
