Is it possible to have your vehicle maintained and serviced at a dealer and have very little show reported on a carfax report? I have a scenario where the seller indicates the differential is dry, etc. however I do not see any service records reported on carfax. Are the discussion of the axcel work a product of hard off roading/major mods or by virtue of simply driving the vehicle an x amount of miles? The vehicle has roughly 90k driven on it.
