without sounding like an arse mate,
every post i've seen you put up so far is a niggle or a complaint about the zed,
must admitm this is the first one where you haven't compared it to the uber quality of your previous audi.
i think what you need to keep in mind is that every car will have its niggles. you either move on and enjoy it. or change cars.
this isn't a 60k sports car its a 30k sports car that competes well with alot of 60k cars.
as i said beife nissan built a very good car, but they built it to a budget.
i think the quality of nissans painting does vary, especial as they put it on very thin.
get some good waxes on and build the layers up it will help to defract this effect. it won't remove it but will help.
