That's a two-edged sword. If you mix to match the current faded state of old paint, then the new paint is early in its fading cycle, whereas the old stuff has done it all and stabilised. As time goes by the colours will drift apart.
If the new paint is mixed to the pantone number or recipe of the original, then they start apart and age together. Slowly, very very slowly.
Reds and maroons are devils for fading, and they tend to go matt with time.
The UV-powered brightening agents in some of those poisonous looking yellows and greens that car makers went for in the 70s and 80s age a lot too, also beware of ultra bright whites.
The full frontal assault is to redo all the paint, and then it will certainly match and age together. Rotate stored sets so that all faces get similar exposure to sunshine.
