Strutto...
First of all it is a bad thing to list the rest of the defects on your vehicle on a public forum, as its been known that they actually "trawl" forums. See NS about a guy got nailed for a FCON V a/m computer which he proudly declared and then got defected by a cop later.
Windscreen... I would ask for a clarification ? IE. why is it not ADR? do you have stickers or something on the windscreen? or have you got a big crack on it?
About the wing.. If it is within the body of the car (not from one side mirror to the next but the actual body of the car) then you can get it cleared very easily from a good DOT. I said good DOT coz the one that is near me is useless. The one at Zilmere was the best I found, if its close to you. The 5mm radius is the nasty one which most of the people will get nailed for, as alot of alumium type wing dont have 5mm end plates..
As to what you have mentioned about the self cleared defect when you didnt do anything about... if you did do something about it, you would have receipts to prove that it was fixed.
I have had the same problem with me old GT wing before, so I've gone through all this crap...
Oh yeah.. the wing defect was $75, 1 point loss and self clearance as well..
