The three ex-fire appliances have been parked outside Turners Auctions, on Portsmouth Dr, awaiting sale after being decommissioned from the Mosgiel, Colac Bay and Bluff fire stations.
Two were part of a national truck auction held yesterday, but were passed in after failing to reach their reserve.
Auctioneer Dwayne Johnston said the International trucks were between 29 and 33 years old.
The former Mosgiel appliance was originally based at the Central Dunedin fire station, Mr Johnston said yesterday.
While lights, sirens, radios, ladders, Fire Service crests, station names and most of the hoses had been removed from the trucks, they retained their pumps.
From about 30 minutes after they were parked on the lot a fortnight ago, the big red trucks had created a lot of interest, Mr Johnston said.
Farmers and transport companies were attracted to them for their powerful pumping capacity, historians were interested in them for their historic value, and one potential buyer was keen to convert one into a camper.
Mr Johnston expected the trucks to sell for between $4000 and $10,000.
