If it were possible to buy a new 1970 compact auto for its inflation adjusted 1970 price (around $14500) or a current typical compact auto your choice would be?
I agree that this doesn't really belong in politics, but the inflation adjusted price is not really accurate. First, most cars in the 1970's, including Toyota's, did not use fuel injection. This meant that the mileage and fuel economy was insufficient by modern standards. Second, the crash ratings of those 1970's cars would make them death traps by modern standards. Even the joke Smart cars have more protection for the occupants than a similar compact car from that era.
By the time you add in all those safety features, and pollution restrictions, and fuel economy requirements, you end up with a car that is much more expensive than the inflation adjusted car you started this thread with.
Volkswagen Beetles for example, inexpensive, reliable, easy to work on, easy to repair and replace. Once you add in all the mandated equipment, now is more expensive, heavier, and granted, more economical with gasoline. It is also safer, and more crashworthy.
The question is what would you want your kids in? A 1970's Toyota Corolla or a 2016 Toyota Corolla? Both have 4 cylinder engines. The modern one is heavier, goes farther on a gallon of gasoline, has reinforced doors to reduce intrusions into the passenger area, crumple zones to help absorb the impact, air bags to help cushion the G-Forces endured in an accident. Preloaded seat belts that automatically tighten when an accident happens. Produces Carbon Dioxide instead of Carbon Monoxide.
You would not only be giving up anti-lock brakes, but giving up disk brakes for drums, which are worse.
Now with all that to consider, you can still get some compact cars in the general ballpark of the price you're talking about. Kia and Hyundai and several other makers have cars in that general price range.
