According to the website TheCostOfLiving.com, the average car cost $605 in 1933. Because of inflation, however, a dollar was worth far more in 1933 than it is today, so the cost was roughly equivalent to $10,214 in 2010 dollars.
The average cost of a car has risen since 1933, in part because modern cars are far more complex than those made at that time. Drivers expect better engine performance, and modern cars handle far better. Regulations and consumer demand also require a number of safety features that didn't exist in 1933. All of these factors play a role in the rise of car costs.
