The wheels were around a grand each corner when new. Not even available now. They don’t come up for sale very often and when they do they fetch good money. As they are forged alloy they are very difficult to straighten if they get any damage so often people are desperate to find one.
Seats are unique to the ZSport too. Can’t get the wing badges either.
If you are tracking it then get a cheap set of wheels, remove the badges and swap the seats out too.
Hi and welcome from a fellow ZSport owner, unfortunately due to my wife’s health and back condition ours has only been used less than 900 miles in the last two years hence in the throws of selling her. But they are a stunning car.
