I just looked and it just had a box checked that said "new vehicle warranty as outlined by manufacturer", and no duration.
I did get the card though which showed 2 years which was the deal I had, $13,721 OTD on a leftover 2016 rxpx 300 and 2 year warranty in may 2017.
I could have gotten 4 years if I bought the 2017 for $3500 more.
