What is a good site to look for used cars in my ar

[slice2020]

I am looking for a used first car that is some where between 1 and 4k and i have been using mostly craigs list, whats a good place to look for these cars i tried ebay and a few others but they are more for 'new' used cars that are mostly 10k and over. Any ideas, craigs list is great i just want more sites to look for cars to open my options.
