You're probably looking for the getKey() method on DataSnapshot:

    mFirebaseRef = new Firebase("https://yours.firebaseio.com");
    mFirebaseRef.addListenerForSingleValueEvent(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            for (DataSnapshot child: dataSnapshot.getChildren()) {
                Log.i("MainActivity", child.getKey());
            }
        }

        @Override
        public void onCancelled(FirebaseError firebaseError) {
            Log.e("MainActivity", "onCancelled", firebaseError.toException());
        }
    });

A few things to note here:

• I changed getChild() in your code to getChildren(), since there is not method getChild() that I'm aware of.
• You should consider using addChildEventListener, which gives you DataSnapshots on the lower-level nodes
• Things will get considerably easier if you create "wrapper classes" for your cars. The Firebase SDK for Android will then automagically unwrap the JSON into instances of that class. See our AndroidChat repo for a good example of this.
