Ferrari has announced it will build one more LaFerrari convertible – bringing the total production run for the hypercar to 210 units. The 210th LaFerrari Aperta will feature a unique livery that will be revealed during the company’s 70th Anniversary celebrations in Maranello, Italy. Only 209 LaFerrari Apertas were originally slated for production, but the automaker has decided to build one more unit for charity. Ferrari did something similar last year, building one more hardtop example of the hybrid hypercar that raised $7 million in support of the National Italian American Foundation Earthquake Relief Fund.

Like the coupe, the convertible will be auctioned off by RM Sotheby’s on September 9, 2017. It is expected to fetch between €3 million to €4 million ($3.54 million USD to $4.72 million USD), although we suspect it will go for much higher than that.
