The white BMW car had an emblem on its licence plate resembling a crest from the Johor Royal family.
Three other European luxury cars, including one Singapore-registered BMW 3 series, probably gave the illusion that the owners were successful businessmen.
But Johor's drug cops, the Narcotics Crime Investigation Department (NCID), were not fooled.
It knew the nine men dealt in a deadly trade: Trafficking drugs from Johor Baru to Singapore.
On Feb 4, the charade was over.
Along with officers from Johor's Royal Malaysian Police, the NCID officers laid simultaneous ambushes at five locations in Johor Baru.
The nine men arrested are believed to belong to a drug syndicate allegedly led by a 46-year-old Singaporean.
The nine men ranged in age from 23 to 46.
Yesterday, Johor Police Chief Mokhtar Shariff described the successful drug busts as a win for drug enforcement agencies in Johor and Singapore.
Mr Mokhtar said at a press conference at the Johor Police headquarters: "I want to emphasise here that the Royal Malaysian Police, especially NCID, has a close working relationship with the Central Narcotics Bureau (CNB).
"We exchange information. And we have a common enemy - drug pushers. Both countries are equally aware of the importance of fighting this problem together."
Of the nine arrested, two were Singaporeans.
Both are aged 46 and are wanted by the Singapore authorities for drug-related offences. Six of the arrested men tested positive for drug use.
