Next UPDATE !!
The old Scott Bonnar site on Port Road has now morphed from being a "Haval" Dealership to becoming the newest Jeep Dealership in Adelaide. It's called "Adelaide City Jeep" and looks set to be there preserving the building for quite some time to come.
It also seems that all the high-rise that was to be built on Port Road has been scrapped for the time being and now with the banks getting tighter on lending, this change of heart in development doesn't surprise me one little bit.
Cheers,
