Vehicle scrubbing is a very important piece to the DealerTrend algorithm. Our goal is to help you market your vehicles online with as much quality information as possible. Since a VIN only has a finite amount of information available, our system looks at all the data available to us about a single vehicle in aggregate. Then based on rules that we have built over the years we determine the exact match vehicle and apply the appropriate features and equipment to it.
One key point that you should be aware of.
1) Our system won't "guess": If left with 2 or more possible exact matches we error on the side of safety. If you find that you have vehicles that are missing information you can enhance the data by adding things like 'trim', model code, etc.
