Paintwork Protection - is it worth it?

[Sortie 10]

I am on the point of buying a 2 year old BMW Z4 and have been offered "Silver Seal Total Car Protection" for £249. Seems a lot of cash for what appears to be serious car wash/wax.
Does anyone have any experience of this or any other similar treatment? Is a thorough Autoglym waxing a cheaper equivalent alternative?
Any other recommendations - other firms or diy treatments would be appreciated.

I wouldnt think its worth it - I have a Z4 and the finish is perfect afer a good wash.... ( by the way - my sister is selling hers if youre interested) 2.2 in blue - loaded with loads of toys ( 182 alloys, wind deflector, leather etc) and she wants about 21k.
