Yago, Man, I really wanted to stay out of this. I offered up a free price analysis to a dealer that was facing some issues. That's it - Just willing to do a favor.
First let me start by saying I like Craigslist. But every issue faced by every dealer can't be solved with the single answer of "Craigslist".
"When all you own is a hammer, every problem starts looking like a nail."
I clicked many of the links you provided including:
2004 f150 blue 4x4 xlt
seattle cars & trucks - all classifieds "f150 2004 blue 4x4 xlt" - craigslist=
I found 7 listings, but only 4 were actually for F-150's. Of those 4 listings, 3 were for the same vehicle - duplicates. There were only 2 2004 F-150s. I don't think either are blue. Only one had a picture (it looks black, but the private seller will take a BLUE Eddie Bauer Bronco in Trade). The vehicle showing 3 times was one of your listings. No color is listed and there is no picture, but it is priced $4400 below Kelly BLUE Book!
I did my own search on AutoTrader.com:
2004 F-150 zip 98012 - 75 mile radius
My search returned 9 listings - there were no duplicates. A the the bottom was a handy summary:
Range of prices within this search:
Highest Price: $22,950
Lowest Price: $7,988
Average Price: $15,184
If all I need is a very rough price range, I think I'd use the ATC results. The 2 Craigslist postings were both for vehicles priced well below the ATC average. If I was selling lower dollar units I would check those listings also.
When dealers need a much more detailed and thorough ranking of pricing rather than a rough range of prices, they come to us. Mileage-adjusted ranking down to trim, options, CarFax and certification status is a very time consuming process to do manually without a good tool.
My intention is to make this my last post on this matter. I don't want to get into a
Vendor War.
