Same here, logged on and the option was there on the right hand side saying you can extend for a further 2 years. Just press continue and agree to terms and conditions and 2 year extension was granted with the option of renewing at any time during the 2 year extension. I have 16000 miles on the clock with only 3 weeks left of the 3 year lease so maybe that has something to do with having the extension option offered.
