Pretty sure you can definitely extend if either (or both) of the following are true.
- Less than 20,000 miles on the clock at the end of the 3 years
- Original Advanced Payment of £2000 or more
You also get the choice of extending by 1 year or 2 – general wisdom is always take the 2 year option. You cannot extend after 4 years for the additional year AND you can order a new car (and take delivery) at any point during the extension. You also get a higher good condition bonus if you complete a full year (or two) of the extension.
