Ah good to have someone nearby! I'm below par when it comes to my automechanical knowledge, trying to improve it and do some work on the Z once I'm 100% sure I know what I'm doing. Do you do much work on your own? (I'm guessing your're currently driving the Jag).
The link sends me to a list of about a dozen Zs on Pistonheads, may be a cookies issue or something (I'm a network engineer by trade), which do you have an eye on?
