@mike, under certain circumstances you can extend your lease up to 2 years if there is nothing on the scheme that floats your boat(looking at the list this morning) and wait until you do find your perfect match, you can change at any time during those 2 years so no pressure.
I am due to change around the same time, and looking at the list today I am thinking of extending too.
Not going to get anything like my Octavia VRS DSG in the near future!!
