BADVIN is a vehicle history report database for consumer protection purposes.
We provide sales history and maintenance records of vehicles. You can see recent sales data including sale prices and photos, car condition, historical damages, number of owners, odometer readings, and other important information.
We also use artificial intelligence to automatically flag cars for potential odometer rollbacks and suspicious sales activities.
According to our research, there are thousands of cars with rolled back odometer and "washed" titles on the market today. Don't be a victim, check the car with BADVIN before contacting seller.
We helped hundreds of people to save thousands of dollars. Read testimonials in reviews section.
