* New vs. Used: The average price of a new car will be significantly higher than the average price of a used car.
* Type of Car: A luxury sedan will cost far more than a compact car.
* Location: Prices vary by region and even local market conditions.
* Data Source: Different organizations use different methodologies to calculate averages, leading to varying results.
To find a relevant average, you'd need to specify which type of car (new or used) and ideally consult data from sources like Kelley Blue Book (KBB) or Edmunds, which track car prices and may have historical data for 2011. Even then, you'll find a range rather than a precise single number.
