Peckham Crew, sir? Cash will do nicely.
Following a few links from the Disposal Services Agency will bring you to Witham Specialist Vehicles, disposers of ex-government vehicles. Five grand in rolls of notes in a JB Sports bag will buy you an armoured Vauxhall Omega 'Driver and passengers protected for 7.62. Also Roof and floor protection for blast and shot ... run-flat tyres etc.'
Just the thing for a spot of crack dealing. Or a drive-by. And those tyres will mean you can run over police 'stingers' with immunity.
(Tx to dizzy for the DSA press announcement heads-up)
