Audi A6 2.0 170bhp

Worth knowing

• A lot of kilometres: 338,000 km, about 1.3 times what a 17-year-old car usually has. Ask for the service history, and when the timing belt and clutch were last done.
• An older car: 17 years old. Cars over ten years need an NCT every year, and repairs and parts weigh more in what it costs to keep.
• The NCT runs out in January 2027: budget for the test and any repairs it asks for.
