He decided to fight the accusation after he received his court summons the same day a group of travellers set up a camp in the car park of his company.

The married man, from Brentwood, Essex said: "I was fed up, like most motorists, of being a law-abiding citizen but a soft target for the traffic police.

"When I saw the travellers in the car park when I'm working on a Sunday it made me quite incensed.

"I'm a guy who pays his taxes and sticks to the law, but I'm stuck at work with travellers in the car park and the police won't touch them.

"Why should I pay this speeding fine while they would get away with it? I'm pleased at the result, but I wish that the police could do a better job when it comes to real crimes against people."

Mr Mills bought the blue DeLorean at auction for £22,000 in 2004 and said the 34-year-old car is "a little rattly" with just over 13,000 miles on the clock.

The DeLorean is a sports car manufactured by John DeLorean's DeLorean Motor Company for the American market from 1981 to 1983 and features gull-wing doors.

The car became widely known and iconic for its appearance and was modified as a time machine in the Back to the Future film trilogy.
