The Coca-Cola dome, Entertainment venue at Northgate Shopping Centre, Johannesburg, South Africa.

The WeBuyCars Dome, formerly the Coca-Cola Dome, is a circular domed hall in North Riding, Randburg, north of Johannesburg. Its roof is built from concentric metal rings and radial beams converging on a central hub, with a band of alternating dark and light vertical slats between the upper and lower rings. Banners hang from the lower ring above tiered seating that rings the floor, now a WeBuyCars showroom of about 11,000 square metres holding around 2,000 vehicles.

The venue opened on April 8, 1998, with a Diana Ross concert attended by around 15,000 people and a surprise appearance by Nelson Mandela. This opening event marked the beginning of its history as a major cultural space in Johannesburg.

The venue's name changed with its sponsors: it opened as the MTN Sundome, became the Coca-Cola Dome, then the TicketPro Dome, and since 2021 bears the name of the car dealer WeBuyCars. Cassper Nyovest's sold-out #FillUpTheDome show in 2015 was the first by a South African hip hop act.

The Dome stands on the corner of Olievenhout Avenue and Northumberland Road in North Riding, next to Northgate Shopping Centre and just west of the N1 Western Bypass. It is 45 km from O. R. Tambo International Airport, 16 km from Lanseria Airport and 20 km from Sandton. Visitors enter the showroom at floor level, where the cars are displayed.

In 2021, the venue transformed into a specialized automotive showroom capable of displaying over 1,000 vehicles at once. This conversion shows how the space adapted to new purposes.
