Your first car's usually going to be what ever you can afford that is cheap on fuel and easily maintainable. Don't expect to hold an attachment to it for too long.
Once you find some cars in your price range, search up the models and common problems for the models.
Naturally aspirated small petrol engines are going to be less maintenance, such as small hatch backs.
Don't forget you're learning in it, so you're bound to have dings / scratches, so it doesn't need to be 100% perfect, as long as there's no paint-fade or rust.
Keep the oil fresh (every 10k KMs) and keep the paint washed+waxed and It'll go far.
