Thanks folks. The radiator, diff, brake and trans fluids sound like a good idea. Makes for a good baseline anyway

Any special "Mercedes only" fluids (besides oil)that anyone recommends.

diff fluid......weight/type/brand?
trans fluid....weight/type/brand?
brake fluid....weight/type/brand?
radiaitor fluid...weight/type/brand?

I use non synthetic oils in my Miata's and just change often. I am not a huge fan of synthetics because I change the fluids often. Usually at shorter intervals than recommended.
