Question about car loan during bankruptcy.

So I just filed for bankruptcy today and got my case number. I am currently current with my car loan but I am upside down about $5,000 cars worth about $7000 I owe about 12000$. I have seen that I can stop making my payments and they cannot repossess my car until we get the final judgment on the bankruptcy. Is this true? I was thinking of not making my payment saving the money and getting a newer car. According to some of the stuff I've seen on carvana I could actually lower my car payment and get a newer car with less miles.
