Checking a LR dealer service history is very simple if you are able to call the dealership and verify. A lot of independent garages do not keep records, just stamp the books. But one way to check if a car has been serviced, just look at the condition of the air filter, usually it is just a few clips, if the owner say it has been serviced, but the air filter says otherwise, take what ever he says with a pinch of salt. Also the fuel filter can be visually checked, old filters usually look tatty, compared to a shiny new one. The same for the oil filter, if it is a metal spin on, see if it still has that new shine on it, or if it looks like it has been on there for a few years! But more manufacturers are turning to the paper insert oil filters, which makes it difficult to check their condition. hope that helps some one.
