Maintenance Requirement for 1981 300D?

[irianjim]

I just bought a 1981 300D at an auction with about 186,000 miles on it. It has books with stamps until about 140,000 miles. I got a great car - everything works, no dents, no rust, good original paint and a flawless interior. I've put about a thousand miles on it and the car runs excellent. I've changed all the fluids on it , but I am not sure what else I should do. I sure would appreciate any advise on what else I should check and any additional maintenance I should consider at this point to ensure that it continues to run well for a long time. Also, if anyone knows of a good Mercedes mechanic in the Oklahoma City area, I sure would appreciate a name.

Any advice would be appreciated.

Thanks, Jim
