2017 Pagani Zonda Riviera = $5.5 million

Highlight of the Dubai International Motor Show was the 2017 Pagani Zonda Riviera, which sold for $5.5m. The Zonda Riviera started life as an ordinary Zonda F - but a car accident sent it back to Pagani for repair & upgrades. The car went from Zonda to one-of-a-kind Riviera. Upgrades include new carbon fiber body panels, a roof scoop, a carbon fiber rear wing, carbon black wheels and carbon fiber front canards. Pagani upgraded the car's 7.3 litre engine to produce 760hp, and complimented that with a brand new exhaust system.
