There are so many variables that it is not really possible to
designate any particular result as "correct" and everything else "incorrect". This applies to the model, the scale, the standard used, the definition of "correct" color, the light illuminating the car/model, the color temperature of the photography, the limitations and calibration of the monitor or magazine used to reproduce the images, the so-called "scale effect", the age and accuracy of the colors and color standard used, the sensitivities of each human eye, etc, etc, etc.One answer ? Buy what you like, be happy and don't assume everything else must be incorrect. Since this is (or is supposed to be) a enjoyable and relaxing hobby, just have fun !
