A parabolic reflector helps...
I don't actually have a ZZ, but my friend lent me his SE so I could fix it (it's working now), and I wasn't impressed with the range either.
I imagine (haven't tried it yet) that soldering a better antenna onto the car might help, but the simplest thing is probably to make a parabolic reflector for the Tx antenna. Think about it - most of the signal is going off in other directions... the attached file is my pattern - make two and wrap a cardboard strip around it. then cover the inside with aluminum foil and punch the antenna through. the antenna will still work normally for normal range, but as long as the reflector is pointed at the car, it should be able to go at least half as far again, if not more.
