Extended warranty

Hello,

Had an email from Skoda asking if I want to take out an extended warranty as the car is 3 yrs old next month..

There is only a 3 gbp difference between all component cover and named component cover, but it's a bit confusing regarding the maximum claim limits on each policy

I guess all component cover is the one to go for but would appreciate comments from anyone who has taken out a policy.

Thanks.
