Buying Tips for 2017 Toyota Avensis Mk3 (T27)

  • Petrol manual cars are the safest bet. Diesel cars need evidence of motorway use and DPF-friendly servicing.
  • Listen for steering-column or intermediate-shaft knocks on the test drive, especially over patched-up town roads.
  • If buying a CVT petrol, make sure it pulls away smoothly and ideally has had fluid changes despite the "sealed for life" marketing.
