Ok, so I have now sold my Mondeo and am ready to purchase a Z. I have up to 20k to spend and the dilema I am in is that currently there are no 57 or newer plate Z's available for sale privately. Ideally I wanted that one so I'd have the latest engine. However, there are a number of pre-57 plate Z's available for around the 18k mark which have everything I want except the engine. Is there that much of a noticeable difference between the two that you think it would be worth waiting a few weeks (I have my partners car to use in the meantime) for the right one to become available? Thanks all.
