The I-Team ran the vehicle identification numbers (VINs) of used cars and light trucks currently for sale at dealers across Canada through the CarFax website, and compared the results with CarProof reports for the same vehicles.
U.S.-based CarFax and CarProof of London, Ont., are companies that provide reports to consumers and businesses on used vehicles in Canada and the United States. Users enter the VINs of their vehicle into the websites and, for a cost, both companies issue reports on collisions as well as the number of owners and data related to floods, fires and liens.
In the I-Team investigation, reports for cars from Manitoba, Ontario, Quebec and the United States came back with matching information, but reports for vehicles originating in Saskatchewan, Alberta and British Columbia showed variations in data.
In one example, a 2010 Honda CR-V EX from British Columbia, CarProof reported $3,554.83 in damages that CarFax did not show.
A vehicle from Saskatchewan, a Dodge Caravan, had a clean CarFax report, while CarProof revealed $17,179 worth of collision damage.
In Alberta, a Buick Allure CXL had a CarProof report showing $940.44 in damage, but CarFax showed no collisions.
CarProof and CarFax reports for selected vehicles
Car owner shocked to find $20K in damages
A customer of a Winnipeg used car dealership got a shock when the CarFax report he depended on to purchase a vehicle at The Car Store on Main Street missed almost $20,000 worth of damages.
Trevor Levasseur bought a 2008 Volkswagen Jetta in February last year, signing a financing agreement totalling $14,000 with 29.9 per cent interest for six years, after the dealership provided him with a CarFax report that showed no damage to the vehicle.
But six months later, when Levasseur decided to sell the Jetta, he discovered the damages on a CarProof report.
The report showed there were two collisions within the last four years in Saskatchewan, where the car originated. One accident netted damage of almost $17,000.
Car Store manager Tony Panidisz told CBC News they were also relying on the CarFax report. He declined to comment further.
Levasseur told CBC News he depended on the report to make an educated decision.
“What made me confident was CarFax that they showed me,” he said.
CarFax can't explain discrepancies
CarFax spokesman Chris Basso told CBC News the company couldn’t explain why there are discrepancies in the data, but once information is brought to their attention, they add it to their reports.
“I can tell you what we have, which is 81,000 sources and a database that's comprised of 12-and-a-half billion records,” he said.
The I-Team sent the results of its investigation to CarFax, and Basso did not want to comment further.
CarProof's director of product management, Shawn Vording, says each province requires his company to mine the data differently.
For example, Manitoba Public Insurance reports collision information directly to CarProof and CarFax.
Ontario has a system in which auto insurance is provided by private insurers, and companies are required to submit claims to a central database, which CarProof accesses.
Saskatchewan requires an extra step — CarProof doesn’t receive the data directly, but obtains information about insurance claims by mining that data from Saskatchewan General Insurance's website, where that information is publicly available.
In cases where the Saskatchewan data is not on the report, an alert appears on the CarProof report indicating that records have been found in Saskatchewan and it directs customers to the SGI website. Such an alert does not appear on CarFax reports.
In B.C., dealers and consumers are required to purchase an additional CarProof B.C. report that costs an additional $20.
That is because the Insurance Corporation of British Columbia (ICBC), the province's public auto insurer, charges CarProof extra for access to its data.
“We know that it offers the best data, and it's the most comprehensive report that's available,” Vording said of CarProof's reports.
“If there are dealers that are choosing not to use our report, they're also choosing then not to have the most comprehensive report."
