A cool secret interior leather (most likely a glitch):
- Go to Build Your Own 2016 340i
- Pick Estoril Blue exterior
- Pick Saddle Brown Dakota Leather with Dark Brown Highlight
- Go to Packages
- Under M Sport Package option, pick "Aluminum Hexagon Trim with Estoril Blue matte highlight"
- VOI-LA!!! You just got a free of charge, gorgeous white leather for your 340i. It's not oyster color that's for sure.
