First time car buyer, no credit, no cosigner (possible cosigner)?

I wanted to know if it's truly possible to get a car without any credit or a cosigner, my sister could be a possible cosigner but she's young just like me but in a way not sure if I can trust her. I believe I can makes payments if I'm under her. But I'm just worried about one day if she might mess up on herself if that will affect me etc…

But anywho she was able to get her car without a cosigner because my mom has bad credit, she paid cash and is financing I was wondering if I do the same I can get a car too. I wanted to trade in a van and put a down payment of $1000-$2000 down. As long as I faithfully pay monthly I can get it right?

Oh btw the car I want is a 2010 Honda Accord ex-l like $14,000 my dad said a car dealer like that is "lying" that I need a cosigner so I'm kinda confused do I need a consigner or no? Is it possible please help. Oh also I make like $700 almost every check so he says I qualify so
