@Stefan nice find. Do you need to pay for the service for more accurate data? I ask because I just ran 2 different Mercedes and the "free" VIN check was terribly wrong.
From what my team tells me, it has data for about 60% of the cars and it depends on the year, make and if the vehicle was sold retail in us. It also appears that they are working hard on adding new info to their database quite often. For sure not a perfect solution but it is useful.
