Have you had the car from new, and who serviced it ? Full service history is not worth the paper it is written on, most people who service their own cars know that the work has actually been done ( which is not the case if car serviced by dealer ) and exactly what oil and parts have been used. Apart from the time i got a free service contract from Honda when I bought a car I have always done my own servicing - I have bought cars with Honda main dealer FSH and the cabin and engine air filters had obviously never been changed and oil filter quite rusty - so that never been changed either.
