The AUDI A6 (2011-15) 5DR AVANT 2.0 TDI ULTRA DPFR SS 190 EU6 S LINE STRON AUTO7 is a premium large estate, or Avant, combining executive comfort and family space. In the UK, it is a practical, more upmarket alternative to mainstream estates such as the Ford Mondeo.

Average private-sale valuation was £8,100; recorded mileage averaged 109,000, with about 10,000 miles added yearly and roughly three previous keepers. Its 2.0-litre diesel and automatic gearbox suit commuting and longer trips; the roomy boot and rear seats make it a practical choice for families and travelling professionals.

Check service history and condition carefully, particularly at higher mileages.
