Millennium Falcon outdated???
Cars from the 1910s can still drive on today's roads in their original state, albeit not to the standard of a modern car.
However, they could be fitted with fully modern engines, running gear, brakes etc., yet still maintain their original outward appearance. This is done to things like e-types, cobras etc., and could be done to older cars if someone wanted to.
The Falcon could quite easily have been similarly refitted during the hundred years.
