Hi, Google RPO code and VIN number. There are a couple of different ones out there, some cost money and some are free. I used the free ones but don't remember the web address sorry.
I do not think that there is anyone here that is currently running VIN numbers, but what you can do is take a picture of the RPO code build data plate that is in your glove box and use the thread below to decode all of the RPO codes. It takes a bit longer to do, but it is something that you can do yourself.
