Hello,
If/when all the maps are made 2084-style&technology compliant, there should be a few never-to-use-again models left aside.
In such distant days, I doubt that even in the most poor land, a 20th century truck may still be operational.
However, one of the backwaters area map could become an "old tech" conservation site, and even feature an eco-museum about 20th century. It would be like a tribute to all the modelers who contributed the game maps.
It could feature a house, a outdoor park for rusty machines, and a cluttered wreckage nearby.
