Regarding the 380 question.

This reply is not so much about mpg, but a word of caution.

I may stand corrected on the year, but I believe the '84 model was refitted with a double-row timing chain. Earlier models had a single-row timing chain and these were known to fail.

Check thru the archives here to ensure I'm right about the year MB switched to a double-row timing chain. I you find a 380 you like, make sure it's equipped with such.
