BoostNbenz: Thank you for the link! That thread is great – just what the doctor ordered.
PSFred: Years ago, I rode in a ’87 300D and it was quite impressive. (probably what got me to even ever consider a diesel at all). I’m glad to hear of your good experience with yours – question: is the engine all original, or has the head been replaced?
Also, is the 2.5 (602 engine) significantly less powerful than the 603? (I apologize for being lazy – I could research that myself…

)
Thanks again guys!
Glenn
