The Pagani Zonda ended its 18-year run last year, but founder Horatio Pagani isn't quite ready to shut off the tap just yet. The last Zonda is also the most expensive — and not just the most expensive Zonda. At a reported $17.5 million, the HP Barchetta is also the world record holder for the priciest new car ever. The eight-figure price gets you a 7.3-liter, normally aspirated AMG V12 that puts out 760 horsepower mated to a six-speed manual transmission and a roofless design that might be the best use of the Zonda's lines yet. Only three will be made — one for Horatio himself and two more that have already been spoken for, marking a fitting end for one of the world's great supercars.
