15. Rear Jump Seats
Rear jump seats, tucked into the beds of pickups or the cargo space of wagons, were designed as space-saving solutions for occasional passengers.
While hardly comfortable for long journeys, these fold-down perches have become beloved oddities among collectors.
At car shows and meets, original jump seats are proudly displayed, celebrated for their quirky engineering and undeniable charm—a reminder of a time when creative packaging took priority over pure comfort.
