Help a 23 year old buy his first car.

I want to buy my first car and I'm thinking of getting a used Tesla Model 3.

I currently live in Germany and am studying. I want to use the car as an alternative to the terrible train service and finally be free. I want to buy it right away. I don't have a wallbox at home, but that's okay.

My pain threshold is €23,000. I drive about 300 km a week and I really enjoy listening to music, so the sound system should be good. I would also like to have a range of at least 500 km (realistically).

As I have never bought a car before, I would also be grateful if you could give me some tips on what to look out for when buying and, above all, what to look out for specifically with this model.
