Minutes after buying a new car, danger driver McKenzie Stephenson "wrecked" a great-grandmother's life by leaving her seriously injured.
Even during a test drive of the Vauxhall Astra, the 21-year-old had broken speed limits and tailgated other motorists, a court heard.
Then, just after completing the purchase of the car, he caused a collision which left a passenger in the other car with injuries including broken ribs and a fractured breastbone.
Newcastle Crown Court heard Stephenson then tried to dispose of the car at a scrapyard to evade justice.
He was found guilty after a trial of causing serious injury by dangerous driving, dangerous driving and doing acts intended to pervert the course of justice and had previously admitted having no licence and insurance.
Now Stephpenson, of Aiden Grove, Ellington, Northumberland, has been jailed for two years for the offences, which took place in Ashington last October.
Recorder Simon Kealey QC sentenced Stephenson to two years behind bars with a three year driving ban.

The judge told him: "During the course of the test drive, you drove that vehicle at excessive speed in a residential area, you were involved in tailgating of other vehicles.
"Having bought the vehicle you then went on to drive dangerously, within a few minutes of that purchase."
The victim was a passenger in a car Stephenson ploughed into when he pulled straight out of a junction on the A1068 near Ashington, Northumberland, "without any real consideration of other road users".
The pensioner suffered three broken ribs, a fractured breastbone and swollen knee.
The court heard she needed follow up hospital appointments, had problems with sleeping and needed strong painkillers.
Recorder Kealey added: "She describes it, at her stage in life, as wrecking her life.
"All of which can be laid fairly and squarely at the door of you and your dangerous driving."
Angus Taylor, defending, said Stephenson does not have bad record, lives with a partner and has a history of anxiety and depression.
