Frankie,
I currently use Corys Ultra High Gloss Piano Polish on the Burlwood trim in the MB. Corys provides a very high Glossy Finish, it also has UV protectors to prevent sun damage. Also very easy to use and doesn't leave any residue. Give it a try, you won't be disappointed.
Do a google search to find a dealer. You can also try contacting local Piano Shops, many carry it or will order it for you. Cost is about $13.00/Bottle which should last 1 year or more depending on how often the car is driven.
