(steel is still prescribed by type by design engineers and faithfully alloyed by the steel mills to spec. (same steel alloy = no difference/new or old))

*Rust may be hidden under extensive use of plastic outer body panels (plausibly an apparent but unfounded supposition/not actual)
 
 
*Cars are more aggressively coated these days. Galvanizing (explain).

*More salt is used on roads these days.
*Progressive evolution of engineered 'self rinsing' technology, such as strategically designed/placed  drain holes to allow rain or wash water to purge body cavities of moisture absorbing rust producing sediments, moreover, robotic assembly methods to lessen the possibility of human error which may compromise the operation of such a design by 'less than precise' assembly. eg; the human worker adds an over-sized glob of body filler next to a fender well drain hole which inadvertently clogs it, causing the fender well to hold moisture laden debris instead. (eg: AMC Javelin)
 
*Electrolysis due to some older cars (British/'Lucas') having 'positive ground' electrical systems -where the car's electrical system is basically all 'ground wires' instead. (eg: AMC Metropolitan assembled by Austin Motor Company in Longbridge, England -neither were they dipped in a rust preventing primer bath, then they were shipped in ocean salt air to be sold in USA)
