Paul Stewart Steadman
When questioned by officers Steadman said he had been to Dunkirk for the day to look at a property. Officers then searched the vehicle and using a camera scope were able to see a green and orange plastic bag behind the rear seat bulkhead.
A key fob found in Steadman's jacket allowed access via a metal plate to the area and the bag. Three taped packages were found in the bag which gave positive reactions to a test for cocaine.
The drugs weighed approximately 2.8 kilos and had a potential estimated street value of £400,000.
Steadman was arrested and the investigation passed to the National Crime Agency (NCA).
He pleaded guilty at a hearing at Canterbury Crown Court on Tuesday, 29 March 2016 and was sentenced immediately to six years imprisonment.
Paul Morgan, Director of Border Force South East and Europe, said: "This was an excellent detection and I would like to pay tribute to the Border Force officers who play a crucial role in protecting the UK from illegal drugs every day.
"We work closely with law enforcement colleagues, including the NCA, to prevent drug trafficking and do all we can to put those responsible behind bars."
