The Koenigsegg Trevita was indeed one of the most expensive cars in 2010, with a limited production run and diamond-coated carbon fiber bodywork. The Bugatti Veyron Grand Sport, Pagani Zonda Cinque, and Lamborghini Reventón Roadster are all ultra-expensive hypercars but generally priced below the Trevita's exceptional ~$4.8 million price point.
