* New vs. Used: The average price of a new car was considerably higher than a used car.
* Make and Model: Luxury cars averaged far more than economy cars.
* Location: Prices varied geographically.
* Source of data: Different organizations use different methodologies for calculating averages, leading to varying results.
To get a better idea, you'd need to specify whether you're interested in new or used cars, and possibly look at data from sources like Kelley Blue Book (KBB) or Edmunds, which tracked average prices for specific segments at the time. Those sources may have historical data available.
