London-based luxury customization firm, Alchemist, has taken gold-plating to a whole new level with its one-off, 24-carat gold and platinum-leafed Aston martin DB7 that will make its first public appearance at the MPH Motorshow, featuring Top Gear Live at London’s Earls Court from at the end of this month. The blinged-out Aston also comes with seven diamonds embedded in the bodywork.
