No it is not worth it.
The exterior stuff still needs maintainance. It is only a paint sealant, you can do this with Autoglym Extra Gloss Protection or CarLack long life Acryl wax.
The interior fabric can be treated with 303 fabric guard. (32oz should be fine) and will waterproof and protect leather and fabric for years cost about £20 from
www.thepolishingcompany.com
And all the plastics, rubber etc can be protected with 303 Aerospace protectant.

I picked up a brand new Honda FRV a couple of weeks back. Got it home at 11am. Treated all interior plastic with 303 then sprayed the 303 fabric guard on. I then gave it a very quick wash to remove dust (using a lambs wool wash mitt) put Carlack Longlife acryl wax on and left it for 90minutes before removing, sprayed the alloys with Autoglym Alloywheel sealant which is generally good for 4-5 months. I was finished by 5pm (including lunch and cups of teas). While doing this I was able to check the paint over and even found some of the transit protection wax had not been removed completely, this easily came off with some Autoglym Tar Remover and I was able to seal the paint. I have now put a coat of P21S on this and the car looks amazing, far better than when I picked it up.
Honda offered me the SuperGuard treatment cost £295. All it includes is paintsealant, FabricGuard, Supewheels (to keep your alloys nice but if you read the small print it says it must be re-applied 3 or 4 times each year). It also states that bird lime must be removed within 24hours and then the superguard must be re-applied! So at the end of the day this is just as good as the other products available and gives no performance benefits.
The issue is the materials cost about £30-£40 (and you have loads left over to do it again!) but it will take you about 4hours to do a good job. Hence the £250 - £300 charged by the dealership.
You can often get Autoglym lifeshine kits on Ebay for about £25 this includes your interior protectant and a special exterior sealant, glass protection, if you prefer this approach.
So in summary, do it yourself, you will do a better job and you will know the car is perfect, if you spot a problem while doing it you can contact the dealership that day. It does of course mean you wont be able to drive around much when you pick up the vehicle as 303 fabric takes a few hours to dry
