Yes mate thats correct mine is the steel one as the alloy one my mate has simply wouldn't go under a mildly lowered car but was still the same money as the one i got . Maybe the £600 one is a lower alloy one to the alloy one pictured ?
Good luck with the costco though anyway mate im sure it will be more than up to the job
