Have they ever changed the ATF???? In the us that is done at 100k. If it is due, you should have insisted.
Of cotse the salesman will say'if the factory say do it, our techs do it- even if they didn't list it I am sure it was done"....
Even if you don't have a major failure, an alternator here,a window regulator there and a fewcoddsvand ends and 3300 can seem cheap
Keep it as simple as possible...but no simpler.
