Agree. They're intended to document the car and it's state. Subtle editing to make the image look good, but nothing that disguises that state of the car like that 325i e90. Documentary.
Here's a worked example:
Volvo 855-T5 for sale aka "Does my ass look big in this". Please view large - and if you're viewing on mobile device, please say so when commenting.
Now, I've pushed the envelope a bit here;
there's negative space to draw the eye,
I've played a little with our old friend the rule of thirds,
I've used a wide angle lens to accentuate the curves of what most think is a box.
The exaggerated perspective should make the viewer wonder "wow, that really will swallow a wardrobe whole", whilst conveying an honest view of a 20 year old wagon for sale.
Brown towball, scuff on bumper corner, but clean and loved.
It has been edited - a seemless vignette, some adjustment to the blacks, whites, lowered highlights, minor increase saturation, and clarity, and brought up the shadows to light the boot area
I've *not* retouched anything to disguise the state of the car.
And very obviously, I've whipped out the plate for the purposes of this demo.
Your thoughts appreciated. Is this a good looking, honest, sale image? It's one of a series of twenty that includes under-bonnet, boot, 7 seat, and interior shots.
PS: buy my volvo.
PPS: D7000, AF Nikkor 12-24 f4, 12mm 1/60 f11 ISO125. I'd not used this camera body before.
