Looking at buying this! after market warranty needed?

http://www.philsimscarsales.co.uk/GetDealer.do?did=21019&pageid=1

as the advert states has had full audi main dealer service history.

but since i cant find a good deal from a main audi dealer am thinking of going for something like this - http://www.warrantywise.co.uk/ww.sys/whatscovered

am going to get them to throw it in with the purchase, sounds like i can get them down to about 10500 with some kind of warranty

has anyone had experience claiming off aftermarket warranties?

I would like to have peace of mind that im not going to be stuck with a massive garage bill at any time - they also do MOT cover as well, it comes in at around £370 for the year but would like to get them to throw in a 2 year warranty

any advice would be great!!!

they said they would do a 3month one but thats it - whats the difference between extra care and major care from warranty direct?

is it worth going for the extra care?

am going to see if they will throw in 2 years to seal the deal!
