I'm working on getting an M8 and am thinking about getting it in Santorini. I love the Enzian I have, but wouldn't mind something new and different so I might go Santorini for a little variation assuming they won't let me have Laguna Seca and there isn't some exciting stock color for 23. I'm hoping whoever buys my car is local so I can do some comparison videos.
Here's a Santorini M8 vid I found for some additional color comparison.
