Getting a job at a young age?

I’m 17 and studying at college. I want to save up for a car and have some extra money in my pocket but it seems like every job I’m applying for either doesn’t hire people my age or just simply ignores my application. Are there any tips on how I can get a job? And does anyone know of places that might hire people my age?

Edit: Got asked by Tesco for my right to work etc. Hopefully it turns into something. Thanks for all the suggestions👍🏻
