"The worry is you do that with Knox Street. When we started the carpark we were able to offer a fairly cheap all-day rate, which drove the rates down in the city centre for commuters coming in for the whole day.
"You lose control if you sell it."
Knox Street carpark, along with several other assets, was earmarked for possible sale in December last year.
Cr Macpherson said council need to take a long-term view, rather than "will it balance our books this term".
Councillor Garry Mallett said however, if it is to the economic benefit of the city, they should be sold and council should not be property developers.
"I think the best council is the council that does least, and does the things it should be doing properly. I don't think the council should be a property developer. A lot of our developments have been disasters.
"My general theory is the council should be a great provider of core infrastructure, and then get the heck out of it. The council, because it is using other people's money, never ever responds quickly enough to poor performance, consequently council invests other people's money and continually bails out failures.
"There have been some strategic reason why that one has been developed. My understand is the Knox Street one was because the V8s was going to be such a boomer that you would not be able to get a park, you would need that parking."
