My 82 300SD has 380K or so. Original engine and transmission. Although considering its an OM617 engine I have a long time to go. :)

I have 376k on my 87 300TD, 287k on my 87 300SDL, 201k on my 92 400E, and 161k on my 67 230! (Average: 256,250 miles!) New head on the SDL "just because" and rebuilt starters and alternators and a water pump, but original timing chains, etc.

Am planning a 4000 mile west coast trip with the 400E for my son's wedding in September, with just an oil change and summer air in the tires! Would just as easily take the TD! They're keepers!

Oil and filters and rubber parts!
