The design might be 60 years young, but they've only been building them for 50 of those.
If the 172 had kept pace with automotive advances - today, it would be built entirely by robots, with faultless, 100% repetitive precision, contain large amounts of composites and alloys, and high-tech plastics and resins, be 30% more fuel efficient, have a considerably lower drag coefficient, and cost 2/3rds to buy new, of what it did in 1957.
No one builds aircraft like that. Even a 787, while falling into most of your categories, is largely hand built. There just isn't the economy of scale to invest in the high tech manufacturing. As quoted above, the closest thig to your description, a Cirrus, costs twice as much.
