Do not forget that paint technology is changing: a new car is more likely to have the latest waterbased finishes which tend to have better flow, sharpness of gloss and DOI. (they also are a bit softer and so may not look so good ater a while!) So a brand new car with the latest formulation of paint will probably look better than (or maybe just "different") to a new car painted in an older formulation. Over the last few years a lot has happened in the way cars are finished and the car manufacturers are now taking much more care over how they apply the paint in the first place.
Another thing is the tyres: put a new set of tyres on a car and it immediately looks sharper, no matter what the bodywork looks like. like the difference between a new pair of shoes and an old pair that have been polished.
