A woman has failed her British driving theory test 105 times, the Driving Standards Agency has disclosed.
With the test costing £31, the woman from Essex has spent more than £3000 - enough to buy a respectable used car.
Her latest attempt at the exam took place at Ilford, but the result was the same as the previous 104.
No other candidate has come near her tally, though a man in Peterborough has made 84 attempts to date.
The theory exam, which must be passed before a candidate is allowed to take the practical, entails answering at least 43 of 50 multiple-choice questions. Candidates must also take a hazard perception test, where 44 of 75 questions must be answered correctly.
The woman's multiple attempts were met with surprise from motoring groups.
"It is unbelievable," said Andrew Howard, the Automobile Associations's head of road safety.
Robert Gifford, the executive director of the parliamentary advisory council for transport safety, added: "It's hard to comprehend how someone could take the theory test this many times and fail.
"At the same time, Her Majesty's Treasury must be pleased by her persistence since it represents a good income for the government."
