Carmax

Consumers have logged more than 1,500 complaints with the Federal Trade Commission regarding used-car seller CarMax over the past three years, according to the agency's records.

In advertisements that help sell thousands of used cars, CarMax says it pays "rigorous" attention to safety details and checks the road-readiness of each car with a meticulous 125-point inspection prior to sale. There's one big item missing on that checklist, say numerous consumer groups.

The car shopping site CarMax rolled out a new tool called MyCarMax on Thursday that will allow customers "to pre-select any combination of vehicle search criteria" when they're looking for new or used cars. The hype is a bit overblown, though, if you're interested in using MyCarMax to find cars with green features.
