i think you've been very fortunate with your costs, I expect to pay at least £450+ for my 60K service this year, tyres were £145 a piece on the rears & that was from an independent, £180 a piece from lexus, i doubt when it comes to camblet, water pump, cv joints, suspension bushes, steering arms, that these will all be in vectra price range even with 33% increase. If you going to pick up one for less than 10K, then i'd assume its got pretty highish mileage & will be 2005'ish, so it will need in the not too distant future some of the items mentioned being looked at. Just my opinion.
