Ever fancied owning a Rolls-Royce? Well, we have the perfect iPhone app, one that allows you to design your very own Rolls-Royce Ghost.There is a drawback to this of course. While the app is free to download, the car certainly isn't free. In fact, you'll be looking at the best part of £200,000 for one. Still, at least you'll have the app to indulge your fantasy. Or if you want a positive spin, you get the chance to design your dream car in advance of your Lotto numbers coming up.There's no shortage of options for your car either, hardly surprising with the price tag. Once you've accessed the app on either the iPhone or iPod touch, take your pick from 12 paint jobs, three wheel styles, not to mention the style of exhaust tips, the look of the hood, the leather used for the interior, even the wood for the internal detailing and well...much more besides, including a gallery of the Ghost and a video of the supercar in action.Grab it now from the Apple App Store.
