Welcome to the board. Firstly take a look under Goosip on the ZS sub page on the main site - then browse the new 45 threads. I think you will find the car won't be here until 2004 at the earliest. Maybe MGR would like to think it will, but I doubt it - also take a look at the TCV sub forum - this could be the new 45.
I agree that the basic 400/45/ZS has been around for a while, but MGR are still developing the car. Furthermore, there is an "Ultimate" version somewhere around the corner, rumoured to be 230bhp.
Also, take a look at the Monogram scheme just brought in - you can do anything to change the look of the car.
So don't be afraid - you know it makes sense - decisions - which colour - I like Anthracite and Solar Red followed by Trophy Blue on the ZS series.
