The processing AE does on its images is horrific. The "noise" in the images of the TC5 is worse than something you'd see from a cheap camera phone. It's not a problem with the car or how it's prepared, it's just the images almost seem like they're processed to make the car look as old and dull as possible. It's unfortunate, there's a lot to be gained from proper presentation. Here's a picture from AE's TC5 page:
LOL, c'mon. Seriously, guys, buy a digital camera made in the last 30 years, and some free image processing software. :-)
