"The police are actively investigating," he said.
Nelson teacher Kelvin Woodley, who paid a $2500 deposit last October for a 2006 Suzuki Swift priced at $4999, said he received a full $2500 refund from the dealer in two payments, one of $1000 and later the remaining $1500.
"We believe that the newspaper article was what made the difference," he said. "We believe he could see that we were not going to just take it lying down."
But an Auckland couple who paid the dealer a $2800 deposit last March for a 2007 Nissan Tiida priced at $5603 have only received $500 back so far.
The dealer texted the wife on Sunday promising to refund the rest of the money "as soon as more funds come into the company".
"He said, 'If my company goes into receivership you won't get a dollar back,'" she said.
"This guy, according to the police, is still operating. So he is actually scamming more people so he can repay us."
The man uses numerous personal and company names but in all cases known to the Herald he asked customers to pay deposits into an ANZ Bank account named "Kar Guru New Zealand". He asked for 50 per cent deposits to cover the costs of importing the vehicles.
Duffy said last month that anyone selling a car on Trade Me should have the car in New Zealand.
"If the deal seems too good to be true then it probably is," he said. "Legitimate vehicle traders don't typically ask for a 50 per cent deposit to help import the vehicle."
Trade Me announced last week that it would refund people who paid for items that did not turn up under certain conditions, with maximum refunds of $2500, from February 21.
