Buy or sell car on Craigslist

Craigslist Car listing research utility in the form of Firefox Addons and Greasemonkey script.

After you start using it, you will have a pretty good idea about which cars and at what price are good buy.

What it does:

• Appends relevant car Review comments pulled from CarSurvey.org. Making the research effort easy. This information is invaluable for a used car buyer.
• Displays the approximate Price of car at bottom. Information is pulled from Automotive and Motortrend sites.
• Displays the useful factory Recall List for this particular car model.
• Adds a StumbleUpon, facebook links. StumbleUpon lets you add/read rating/review of particular website. Its a good feature.
• If StumbleUpon review comment exists for this car sale posting then it pulls that comment and shows it right there on the page.
• Shows a short list of similar ads on craigslist for the selected car year model. This will provide some guess on what the going rate is.
• A button on top of page to enable / disable this research easily.
• Highlights the words accident / rebuilt / moving. Saves time if you want to skip accident car ads.
• Displays Car reliability information from MSN Autos in a frame.
• Provides link to Canadian Black Book site for useful for people in Canada as this site isn't as popular as kelly blue book in US.
• Displays consumer review and discussion from Edmunds.com.
• If there is a phone number in the post then it makes it easy to do a search of the phone number on Craigslist to find out if the ad poster has posted any other ads. This sometimes help in determining if its moving sale or a ad by a reseller etc.
  

Note: It adds all this information only for most common and popular car make/models.
