EDIT: Yep, I'm just old. Another commenter linked to a "10 cheapest new cars" list and there seems to be a price floor of around $20K. No major manufacturer seems capable of making one cheaper!
Some of those $10k cars in the 90s had more plastic in the bodies than cars today, e.g. Saturn S-series, where all body panels below the belt-line were plastic.
It isn't necessarily the cost savings one might expect though, because steel panels can also be load bearing and part of the crash structure, which is not really practical with plastic panels.
Except with all the safety equipment, crumple zones, airbags, sensors, etc. I would expect an increase in price.
The 1996 Ferrari F355 Spider and the 2025 Hyundai Elantra N both have a 0-60 time of 4.8 seconds.
If you get a big enough dent in a door, a good body shop will offer to replace the outer skin instead of filling with bondo. They cut the weld on the inside of the door all the way around, take off the shell, and epoxy a new one on. The body shop owner told me that the epoxy is actually stronger than the factory weld.

Often this is because the special high strength steels used in vehicles today depend on proper heat treating to attain their strength, and welding can compromise this. Many OEMs even specify panel bonding for repairing particular crash-critical parts of vehicles now because of this.
1. because UHSS is sensitive to heat, and robots are much more accurate in how they heat than Jimmy with a tig torch, and they were programmed by a process engineer, where as Jimmy welds until 'it looks good'.
2. welding may compromise anti-corrosive treatments on the inside of inaccessible cavities, which can lead to corrosion issues

A crappy shop will certainly just weld panels in without any regard for materials engineering, but it results in a crappy repair.
