John and Karen Rowlands say their lives stopped when 18-year-old Andrew lost his life after the vehicle, that had no MOT, flipped and crashed on the A692 in County Durham in June last year.
Dylan Brunton, then aged 17, bought the Daihatsu Terios Tracker for £100 the day before he crashed it while taking three passengers for a joyride at a disused quarry on June 18 last year.
