There are only three ZT-T road-cars for sale at present as far as I know , and only two are RHD and UK registered.
Looking through the "Complete list", member "Mean Green" lists #427 in post #8 here:

The full details of the car may not be available if try to follow the link there, since you are not yet a full-member, but you could always send a PM to him asking for details, if you are currently looking to buy? Alternatively PM your email address to me (Member-name "David"), and I will forward it to the seller, if you wish. I think the car is still available.
I update the Complete List at least twice daily, so you are unlikely to miss much if you keep looking there.
Where are you actually located (roughly) may I ask?
