This is pretty neat, once setup you can access all of your service records that have been performed at the dealer :)

Cool it even shows you what and when warranties will expire...
mine show a few extra miles on the end... I guess that is based off of what was reported on the odo when the vehicle was purchased...

Tells me my VIN is not valid.. LOL

I don't recall having to input my VIN, I think it found me by name and already knew my VIN. :eek:
