New owner advice please

Just bought an F Type  S AWD 3.0 which is 4 years old but only 14000 miles. 

With the purchase comes one year warranty which I would look to extend next year. I would welcome advice on what is best around cost of servicing (are service plans good value?) and what exactly constitutes a dealer that would not nullify the warranty. I can see even for service alone the prices vary dramatically and many service centres advertise to service Jaguar cars.

what advice can you give to a first Jag owner about keeping costs reasonable but within the warranty guidelines ?

i am based in London and there is a service centre in Tottenham and one in Barnet - hoping your advice will stop me getting my trousers pulled down.

any advice at all is welcome !!!!

kind regards
