Those rams are a waste of time for the ZS or any low car IMO. I tried to get mine onto them and it touches the bumper before the wheels touch it.
Depends on where you will use it but you can get, as said, a lift which is basically 2 long flat sections ontop of a sissor type jack. you simply but blocks onto the flat sections at the jacking points and up you go. Will ask dad how much they are as they have a couple in their place for very low cars.
