AutoCheck, owned by Experian, is notable for providing a vehicle "score" — a number and a range — like 85 out of a range of 70-90. This shows how the vehicle compares to other similar cars built that year. It is meant to be a quick way to identify and eliminate vehicles that might have issues, ranging from high mileage to reported accidents.
The scale isn't zero to 100, which can be confusing. We ran a report on a 2015 Honda Civic and it received a score of 82. Sounds like a good car, doesn't it? But this Civic was in a major accident, declared a total loss and issued a salvage title, according to the report. The number that matters is the range and, from there, where the particular car scores. In this case, the range for similar Civics was 88-93. The one we were checking, with a score of 82, was 6 points below the bottom of the range — not a great bet for a used car, in other words. We also ran a report on a 1992 Honda Prelude with a salvage title. It scored 25 out of a range of 31-53. Six points seems to be the deduction for having a salvage title, but the numbers weren't clearly explained.
AutoCheck charges $24.99 for a single report. But few people consider only one used car when they're shopping, so you'd likely opt for the higher-tier plan at $49.99. This gives you access to 25 reports in 21 days. In the past, AutoCheck charged that for unlimited reports. Now, even the top plan limits you to 300 reports. As noted earlier, that costs $99.99.
Our opinion: Although it doesn't quite have the name recognition of Carfax, AutoCheck is worth a look. It's a less expensive alternative for shoppers who plan on running numerous reports. The vehicle score is nice as a quick reference, but don't put too much stock in it.
