I rang about this and decided not to extend as 600.00 is 200.00 per year but on 5 years would loose 100.00 as only 900.00 plus the AP would be higher on new one by then i would expect . So better to change now and look again in 3 years and enjoy another new vehicle, ( to extend lease your vehicle will have to be under 15,ooo miles)
I had just under 20,000 miles they were happy to extend my lease
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
