Looking at used k900's and this is the only used one I've seen with quilted leather seats thats not a 2017. Was it an option at one point? Plus this is the only one i've seen with blue interior. I would like to find one that has brown leather inside.
This article states the Blue and Brown were added but I'm not sure. Might just have to wait for the 2016's to depreciate some more looking to spend around 30k. Just recently graduate college and feel like it's time to get a more "business" type vehicle instead of my 2011 Camaro.
They did make some of the later 2015s with the quilted tuscan brown interior. The first 2015 I looked at before buying mine was black with the brown quilted interior, but it was also in relatively poor condition so I ended up buying one that was white on white as it was essentially brand new with only 1600 miles on it.
