According to this AutoBlog post, ...
And because of that quick depreciation, a regular Joe like you or I can snatch up a high-dollar ride like a Jag or BMW 7-series for (relatively) cheap. Case in point: Link to CarMax listing - 2004 Audi A8 with 55K miles on it for $26,998.The National Automobile Dealers Association (NADA) is reporting that premium luxury vehicles actually have the highest annual depreciation rate. The reason for the stone-dropping value is that luxury car buyers tend to want the latest and greatest. The preference for the next big thing leads to owners turning in their current cars faster than people who will drive a Taurus until its wheels fall off.
I don't know about you but that a pretty great price for a top-of-the-line luxury car that's not even five years old yet.
