CALCULATIONS AND ESTIMATIONS

Based on the above 45 Craiglist's sample sites;

Average number of total car listings per site as of this date
= sum total / number of samples
= 98,460 / 45
= 2,188 car listings per site

Average number of new car listings per site posted this day
= sum total / number of samples
= 13,038 / 45
= 290 car listings per site

If there are a totals of 420 local site listings in the US;

Estimated total number of car listings for sale in the US as of this date
= 420 * 2,188
= 918,960

Estimated total number of new car listings posted this day
= 420 * 290
= 121,800

We used the above figures to calculate average yearly car listings. In one year (equivalent to 365 days), total number of car listings is;

121,800 * 365 days = 44.46 million

According to a 2016 case study report released by LotVantage, "cars listed on Craigslist sold 10 days faster, on average, than those that were not." From a separate report, it revealed that within the used car industry, the average selling time or "length of time it takes to sell a car is 60 days."

Craigslist's car listing average selling time = 60 days - 10 days = 50 days

Hence, the total average number of one selling process in a year
= 365 days / 50 days = 7.3

Estimated number of cars sold in the Craigslist sites annually
= 44.46 million / 7.3
= 6.09 million

Number of cars sold in the Craigslist sites per day
= 6.09 million / 365
= 16,685 cars

If every day, there are 121,800 new car listings and 16,685 cars are sold (assuming that every car sold are deleted on the list), and as of this date there are 918,960 car listings found, then we could estimate that at every given time, the number of car listings for sale from the US Craigslist's sites is 1,024,075.

918,960 + 121,800 - 16,685 = 1,024,075

CONCLUSION

The total Craigslist's websites for the US market is 420 and the estimated number of new car listings from all 420 sites per day is 121,800. As of this date, the total number of car listings, excluding those cars that are considered sold, is 902,275 [918,960-16,685]. From the calculations presented above, we could safely conclude that on average, the total number of cars that are for sale at any given time United States' Craigslist's sites is 1,024,075.
