you could try writing a letter to them and explaining the situation and take some photos of the place to try and prove the poor lighting thing... bring up the whole sedan ute thing aswell I don't like your chances though...
Some autobarns will mix it up for you and stick it in a pressure pack. they just need the paint code. or they can try and match it but I dont know how well they do it.
I think it might be slightly higher then 5500, but not quite 6000. But when you hit you'll know, just make sure you have ya seatbelt on or you'll fly the the windscreen! lol
