It took me about 1 month to get my zed as I wanted a black GT zed with 60 to 70k miles on the clock, good service history, preferably with nismo rear spoiler, lower tax window, etc.... I live in West Yorkshire and I ended up buying mine in Essex (4hrs ish drive, special thanks to my missus) I did tried to get it more locally but it's not always available and some zed can be pretty limited hence I decided to pick it up from Essex.
People here in this forum are very nice and if you give them enough warning, they might help you to view the car locally for you (at your own risk but defo dependable)
Good luck with your search..... If you need help, you know where to ask now 😀
