Adjusted for inflation, cars cost about the same now as they did decades ago. All the objective measurements look better on the new cars. However, they're less fun to drive.

I wonder how much a new Model A Ford would cost today if they were mass produced in a low wage country like China.

As for getting rid of all the unnecessary garbage that goes into new cars, the easy way is to lose two wheels and get a motorcycle. The regulators haven't gone crazy on them (yet) so you can still buy a new vehicle for about five thousand dollars with peppy performance and 60+ mpg. Or you can get one for twenty grand that only gets 35 but will outrun anything short of an Enzo.
