The Southern Mustang Owners Club will display 25 Mustangs in the Lower Octagon on Saturday morning between 9am and 11am.
Club representatives will be on hand to answer any questions about the cars.
There will be a selection of vintage and late model Mustangs on display including Boss, Mach 1, GT, and Roush models.
As the Southern Mustang club is an Invercargill-based club, with some members in Dunedin, many of the cars have rarely been seen here.
The display is part of two full days of activities, which are all based in Dunedin, so there will be more Mustangs than usual on the streets of Dunedin this weekend.
The event is organised by Dunedin Mustang owner Bob King.
