If you're mechanically inclined, I've done a lot of work on my 2006 Crossfire. Everything I have done I have documented with detailed pictures with descriptions. LINK - My Journey with my 2006 roadster All of the links are on the bottom of the first page. (Brakes, Brake hoses, Clearing headlights, etc...)
Anything else would be located in the Technical Section of the forums.
I have a manual transmission, a couple of suggestions for the oil cooler line are; get in touch with Rob at Needswings he might be able to locate one for you. You can also check salvage yards or ebay.
Search for mechanical parts as a 2003 Mercedes-Benz SLK 320.
Best of luck to you!
