An unnamed grand-tourer cabriolet is due to appear in Grand Theft Auto VI, briefly parked beside a meter on the Ocean Drive-style strip in the second trailer and then driving the same road at night in a scroll-driven animation on the promotional website. It reads as a two-door reworking of GTA Online's Windsor Drop with altered front and rear styling, consistent with its apparent Rolls-Royce inspiration.
