The move is part of a crackdown in response to repeated complaints from residents about a garage owner.
The vehicles were being dumped on Parchmore Road in Thornton Heath.
The garage, previously known as Balham Autos, is said to have been disregarding warnings for months.
The council’s antisocial behaviour and enforcement teams took action, removing vehicles that were taking up residents’ parking spaces, blocking pavements, and creating hazards.
Some of the cars had no engines, were without tax or doors, and had sharp, exposed metal edges.
They were also found parked on double yellow lines, and some were left blocking disabled bays.
There were reports of aggressive behaviour towards residents and council staff when the garage was challenged.
The council is now working with the Environment Agency and London Fire Brigade on concerns regarding unlicensed scrap activity and fire safety.
Jason Perry, executive mayor of Croydon, said: “Residents are right to be angry – and so am I.
“What has been happening on Parchmore Road is completely unacceptable.
“For too long, this garage has been allowed to dump dangerous, untaxed, and unroadworthy vehicles on the street, blocking pavements and disabled bays, and making residents feel unsafe.”
He added: “This type of illegal activity attracts more antisocial behaviour and fly-tipping – it tells others the rules do not matter.
“That is why I have taken a zero-tolerance approach.
“This is Broken Windows in action – tackling the signs of neglect before it grows into something worse.”
The council said it would continue to monitor the site and surrounding area, as part of the mayor’s Cleaner Croydon campaign, to reclaim streets, restore pride, and make every community a place residents are proud to call home.
The council has issued a community protection notice and a Section 16 notice, a legal requirement for the business to provide full information about the vehicles and site operation.
This carries an unlimited fine if not complied with.
