A man from Sulby bought a car - and sold it a short time later after being caught by police with no tax or insurance.
Anthony Cawte of Kella Close appeared before magistrates this week.
The hearing at Douglas Courthouse was told the 20 year old bought the black Mitsubishi Colt on October 22 for £100.
But as he drove it home, police stopped him at Ballacraine at 6.10pm, where it emerged the vehicle hadn't been taxed for five months.
Cawte's advocate Paul Glover told the hearing the engineering student had bought the car from a friend for £100 that day.
After he'd been stopped by police officers, he insured the car - before deciding it was unlucky and selling it to another friend.
Mr Glover said his client studies in the UK, but has a job as part of his course and so could afford to pay a financial penalty.
Magistrates fined Cawte a total of £300 and imposed five points on his licence as well as ordering him to pay £50 costs.
