X5 service history query

[Windymiller]

I'm currently looking at a previois-shape 2008 3.0d X5 with 100k and 'full history'

It was with Harry Fairburn in Inverness for a few years, then Sytners Nottingham for a few years after that.
However it's only been serviced at 25k (oil) and 69k (major). I know they have this on demand/variable servicing but that seems like very wide service intervals? I've spoke to both dealers who told me that it appeared to want for nothing, visiting them both about 8 times each for various warranty and parts work, and the car is immaculate and very very well specified.

Neither can tell me if the history is 'as it should be' though - can anyone shed any light on this? There were only 2 previous owners, last being a business.

It's also had one at 88,405 with Sytners last year.

They have another one, less spec, with services at 15k, 32k, 34k, 46k, 63k, 66k, 78k, 94k, 100k, 105k, 106k and 111k, which seems a little excessive! Can it really be that different if one's driven by a tool and one by a granny?
