Ok, I will step in here and give my buck fifty's worth....
The Concourse car (the first in this post) probably does have a $20k paint job on it. For the Pebble Beach Concourse, (which I believe the reflection shows clearly) you are asked to bring your vehicle, not you bring it and enter it. I have attached a composite picture for us to really compare the difference.
In the lower sample image (attached), look at the reflection of the mountain- it is crisp, straight and free from any waves. This is a million dollar car. This car, at some point, has been completely disassembled, meticulously prepped and primed, block sanded prior to painting, color-sanded and rubbed out most likely while still unassembled. Then assembled, and re-detailed. Look at the jambs, and where the body meets the running boards. This caliber of car owners see no bounds in paying for quality. $1000 dollars for a detail is not out of the question, if you can do the job. Be prepared to know how to mask every edge, remove trim pieces, touch-up slight imperfections, prep and polish silver, brass, copper, wood and ivory. In the same aspect of performing, you better know your sh*t before working on one of these babies for the slightest oops, will cost you thousands of dollars in repair.
In the sample of the (I'm guessing) Ford, look at the orange peal - the reflection of the jungle jim has a distinct waviness to it that is uniform. I will go a little bit farther not to nit-pick but to point out things that separate a concourse detail from others -- look at the screws in the fender of the Ford. Having detailed cars specifically for advertising, auto shows and concourse de elegances', It is quite easy for me to know and see the difference. Granted they both are awesome detail jobs, with lots of depth and reflectance, but too compare the two and call it just the bends in the metal or trick photography, to me is ludicrous. For me, driving out on the 18th green at pebble beach was a pinnacle of detailing piste a la resistance. Then seeing the two cars I worked upon drive across the boards, and one taking "best of show" is indescribable for an over obsessed detailing nut... it's kinda like great sex I guess.
I also add please study the shadows on the car taken at Pebble Beach... that picture is taken on the sunny side but not in the direct sun (look behind the spare tire cover and the reflectance off of the door hinge). If one was to shoot a reflectance on the sunny side in the direct sun, the light from the sun would in most cases, be so blinding it would blow out the image.
