To provide a clear, concise and unbiased automobile inspection that serves the needs of both dealers and buyers as a tool that instills trust in the auto-purchase experience.

About Us

Marvin Oliver, founder of OnceOver, is an auto industry expert with 12+ years of sales experience. During that time, he noticed two things consistently lacking in people’s car-buying journey: unbiased, detailed vehicle inspection information and trust in the dealership.


Well, no more. Marvin, a U.S. Army veteran with a bachelor’s degree and MBA from the University of West Florida, created OnceOver to offer dealers an opportunity to build trust by providing the information customers need to make purchases with confidence.
