That's why I mentioned mandated features in the OP. I do think they play a big role, but hey, seatbelts were mandated in '68, catalytic converter in '75. So I guess I was wondering if these features along with features of consumer preference, can explain the lion's share of the increases. It seems to me, however, that certain advancements should be able to offset some or a lot of these costs over time.
The most important thing here is that you are comparing average income to average car price from two different decades.
I'm saying it's not that simple.
For instance, if you use the CPI method of calculation:
In 2006 $2,822 from 1968 would be equal to ~ $16,348.
If you calculate using the unskilled wage method, meaning, in simple terms, how much labor would it take
now versus
then to get the car:
You end up with: $16,789
Both of these figures are below the average car price of 2006.
There are actually many other ways to calculate the relative worth of things or purchasing power from then to now.
That said, and completely aside from the method of calculation, the reason I brought up the concept of a commodity, is due to the fact that commodities are the same no matter what year it is. Copper is copper.
Technology makes it easier to extract, ship, etc, but it's still copper.
A dvd player, in that sense, behaves much like a commodity. It's the same product, (box that plays dvds) but with a more efficient and cheaper means of making a box that plays dvds.
A complex machine like a car, doesn't really work like that. Certain parts of the car (bolts, brackets, hell I actually don't really know) you could argue, are the same as they were in 68, but the overall product is apples versus oranges during a 30 year span, which further complicates the comparison in price.
