Is it ever a good thing to get a car from a buy here pay here dealer?

I am going to be discharged from bankruptcy, my car is being repoed soon, and I need a car, but i do not have a co-signer. a dealer will get me a car but it's a buy here pay here dealer. And I do not have enough money to buy one off the street with cash. What should I do? Got any good stories about those kinds of dealer, will a bank ever give a person in my situation a loan?
