Former luxury car boss Matthew James Duncan has lost his licence but avoided jail time despite two high range drink driving offences in the space of four years.

Duncan, the former chief executive of car retailer Trivett, was caught driving his BMW with a blood alcohol level more than six times the legal limit in Woolloomooloo in November last year.

The local court heard at the time that he was slurring his words, swaying and closing one eye to see clearly when police found him in his car, which was stopped in the middle of the road.

Kings Cross police found the then 39-year-old sitting on the passenger seat while two people offered him water, and several 50ml bottles of vodka littered the vehicle.
