Hi Zak,
Welcome to the Forum.
As Kevin said, try the search to see what others may have said about a particular vendor or getting those particular items. Have a good look through the Technical Manual at the headings and there are some very good parts that will help you maintain your Pagoda.
Also in there you will see a list of Vendors http://www.sl113.org/wiki/Suppliers/Start
There are the usual suspects such as the Mercedes Classic Centre and the US dealers such as Millers and Bud's Benz together with others such as Benz Dr and Scoot who all have there speciality areas that you wil get to know as you watch the going on on the forum. There has just been some very recent discussion on the front pillar window rubbers concerning OEM and Repro rubbers, one with cloth covering (OEM) and the standard cheaper rubber items.
http://www.sl113.org/forums/index.php?topic=17459.0When you get a chance, some photos are always appreciated by everyone.
As a basic member you have access to most but not all areas of the Tech Manual, as a full member you have full access to the Manual as well as receiving the Pagoda Notes and annual Pagoda World publication, something to consider for future. Just my plug for the Forum as one of the Membership Secretaries.
