I have almost purchased a 2005 Toyota from a small dealer. I have done a check via Cartell and I am concerned that it has not been taxed since (expired) Oct 2008. It had a NCT Nov 2008 after expiry of tax, NCT due May 2011. Where has it been for the last 18 months? Mileage looks genuine at 71,000 km. Is there any need to worry? I cannot see anything wrong with the car.
