My husband and I are in our seventies and in 2011 downgraded from a Vectra to a Corsa automatic. We decided on an automatic because both of us are now finding that stiff knees make for uncomfortable driving. However, whilst we are reasonably happy with the Corsa we have discovered that the consumption is not great. We expected this due to it being an automatic but it’s nowhere near the quoted figures. The other problem is that we now realise that it is just a little too small for transporting grandchildren. If we were to trade it in and add about £7500. What would you recommend?
