Britain's fastest speeder in a car is facing jail after admitting clocking up 172mph while taking a new Porsche 911 for a spin.
Timothy Brady, 33, was spotted driving more than 100mph over the limit on a dual carriageway in the £93,000 sports roadster.
He was on a 70mph section of the A420 in Oxfordshire in the 3.6-litre vehicle belonging to the courtesy car firm where he worked as a delivery driver.
At Oxford Crown Court, Brady looked sheepish and spoke nervously to confirm only his name and admit the charge of dangerous driving. He was warned that his joyride is likely to result in a jail term.
