Hello Ewen, firstly the GT looks great.
It took me ages to find this thread but I remembered a new member who was looking for a 350Z auto, ...now I know yours isn't a 350Z but I thought maybe it was worth just asking him if he's interested as yours is an auto after all, in great shape and the closest thing to a Zed.
