Do you know what studio photographers jokingly say about extremely unattractive clients who demand heavy facial retouching on the photos before having their photos taken? "Just turn off the bloody lights!" Unfortunately, this kind of response may apply to some cars.
Leaving the illuminating headlights and taillights of an unattractive car floating in the complete darkness may make the said car appear to be more attractive. It won't always be the case, of course.
Mid to late 80's Ford LTD Crown Victoria deserves this treatment. The first time I watched the 1999 film "The Matrix," a sinister looking black car approaches a crime scene, and it has nice, well positioned taillights. After doing some research to find out what car it is, my eyes decided to self-destruct upon a photo of a LTD Crown Victoria in broad daylight. It looks so much better with the lights off.
What unattractive car looks better once you turn off the lights?
