What Car? says...
If you’re the kind of person who spends their time closing million-dollar deals or planning hostile takeovers, you’ll probably have very little time left over for driving. If there’s a business meeting, a power lunch or a glitzy black-tie gala you need to get to, you simply pay someone else to get behind the wheel.That’s why luxury limousines are the conveyance of choice for the rich and powerful, and the Audi A8 is one of the mainstays of the genre.
Alongside its arch rivals the BMW 7 Series and Mercedes S-Class, it's the go-to choice for anyone who wants a level of luxury above regular saloon cars (such as the smaller Audi A6), but doesn't want or need the elite badge of a Bentley or a Rolls-Royce.
