Uh oh...the conspiracy theorists are on the loose again. Let's see, ATC has 3 letters and NOT has 3 letters. So there you have it; proof positive that ATC does NOT take sold listings off in order to boost listing numbers. Wait...OFF has 3 letters too so now it's indisputable. Gimme a break.
Think about it: at the huge volume level involved, automated data transfer/handling is a given. That's true of cars.com, ATC, Vast, AOL, Yahoo, manufacturer sites, Dealer Specialties, Auto Exact, HomeNet, PimpMyUpload, etc., etc.. When new data is pushed in, it is added to the database. If that data is missing from a subsequent push, it is removed. No conspiracies, no under-handed schemes. BUT (oh look, another word with 3 letters, this must be getting really spooky for all you grassy knoll types), because there are so many different ways of formatting data - and most are incompatible with each other - and so many "hand-offs" of data from one 3rd party company to another, the opportunities for snafus are everywhere.
Here are two "You're not taking my sold cars off" scenarios I had this week. The first one...the dealer's 3rd party inventory vendor was not recognizing sold vehicles in the dealer's DMS. So sold units were still being pushed every day to ATC. The dealer then remembered that he had agreed to manually remove sold cars from their DMS until the DMS/Inventory Vendor problem could be resolved, but he wasn't doing it. ATC not at fault, but first to be blamed.
Second dealer (and this happens a lot)...the manufacturer continues to include vehicles in the Certified feed that is sent to ATC directly from the manufacturer, even though the dealer has reported those vehicles to the manufacturer as sold. ATC not at fault, but first to be blamed. I recommended to the dealer that they have their certified feed from the manufacturer turned off to avoid the problem.
Brian and Alex, rather than accusing your 3rd party vendors of nefarious activities, why don't you provide your ATC rep with specific VIN numbers of vehicles that are still listed which you think should have been removed and have them research why they are still on site. I'll be interested to see the findings posted here on DR.
