I obviously also have vehicles with many more miles on them, and even the older ones have
never been subjected to dealer service.
Like GNBRETT, a dealer would be about the last place I took anything of mine. That includes for recalls. Either I fix whatever needs to be done myself (paying for the parts) or ignore the recalls.
Those things, oil changes, etc., I do when
I want them done. Then make a note in that vehicle's log book of what was done and when.
If I were you, as soon as you get that car home, I'd check all the fluids. Ideally replace them all (except for the transmission), and put magnetic level and/or drain plugs in every orifice you find. Start fresh, if you will, then count your blessings if everything checks out and the car was never dealer serviced.
