Twenty-five Mustangs ranging from a black and gold 1966 model to a Tweety Bird yellow 2016 model were on display during a weekend of activities in Dunedin for the Southern Mustang Club.
Event organiser Robert King, of Dunedin, said Mustang owners tended to be an eclectic group with two things in common.
''We are all probably on the wrong side of 45 and the good side of 70.
''And we love Mustangs.''
He had owned his green and black 1970 Boss 302 for about four years, but wanted it for much longer.
''When I was a teenager, '69 and '70 models were racing and just the noise and the style of them spoke to me.''
His American-imported Boss was no more expensive to run than a new car, and parts were cheap and easily available, he said.
The sight of a Mustang rally always attracted a reaction from the public.
''We get a lot of waves and people smile.
''Some people drop their mouth open which is nice.''
Style sometimes came before comfort when travelling in the Boss, Mr King said.
''I wouldn't say mine was nice to drive.
''It's very loud which I like, but after three hours in it I'm ready to get out.''
The colourful cars stood out against the black sky, and a steady stream of onlookers stopped to check them out, despite persistent drizzle.
The Southern Mustang Club completed a rally around the peninsula and visited two Dunedin garages before driving to Balclutha yesterday.
