I don't often post pictures of my wife's car, but I could not resist. I just polished it and applied Wolfgang's Uber Ceramic Coating yesterday. Her car looks better now than it did when it was brand new. The fact that it only has 30k kms on it (18k miles) might also be a factor, because the paint is in near perfect condition. It's not bad at all for a nearly seven year old car! Cheers.
Also, because I can, I include a picture of my daily driver. It also has had the Wolfgang treatment.
