The WeBuyCars Dome, previously known as the TicketPro Dome, Coca-Cola Dome, The Dome at Northgate, and MTN Sundome, is a defunct indoor arena and car showroom located in Randburg, north of Johannesburg, South Africa. The showroom accommodates over 1,000 vehicles and covers about 11,000 square metres. The Dome opened on 8 April 1998 with a concert by Diana Ross in front of a 15,000 strong audience. Nelson Mandela made a surprise appearance on stage during the official opening. The arena closed on 7 September 2021 due to being sold; as of March 2022, it is now used as a car showroom.
