As my never ending search for Merkur-related information proceeds, I will share my findings with you!
The MCA forum
OPMD - A pretty good selection of Merkur Parts. I ordered their coolant hose replacement set and it was fine!
BAT inc - Some like 'em, some don't. I haven't had too much trouble, and would reccomend them
Rapido - Ask for "Russ." Their prices are a bit high, but they're very knowledgable.
North American Cosworth Specialists - these guys are just getting going, but have a lot of great parts for the XR!

A neat interactive marketing program that Ford produced. You can compare the XR with a Supra and a few other cars. (Don't worry, it's Virus Free!) You need WinZip or another extracting software to use this.
A picture of a nice black XR identical to Mine! Taken at Carlisle 2002!
A great writeup about brakes
Merkur Encyclopedia - without this hundreds of XR's wouldn't be running
Merkur Owners Group - an amazing compilation of fellow Merkur owners. This is an amazing resource. But be forewarned, do not join if all you plan to do is take - you will deplete the resources! Post as well!
Merkur Club of America - a national collection of Merkur owners, a great resource, and links to Carisle 2003!
Merkur Desktop - A very extensive list of links and info!
