I own a 1985 300d turbodiesel California with 220,000 miles.

Need honest mechanics in the north Nashville, TN area, any suggestions?

What mpg should I expect for my 300d turbo? (currently get 22mpg city/hwy)

Any way to increase the mpg?

Any Nashville area mercedes owners groups?

Any brand suggestions for factory radio/tape replacement with a radio/cd? (Factory radio/tape has issues)
