ah thanks a lot guys...My choices are between the 92 300D 2.5 turbo and the 84 300SD. I noticed the 92 SD on the list to avoid so i just wanted to mention that. Good to know it's not the same as the car I'm looking at. I'm going to run wvo, not biodiesel, so thanks for letting me know i dont need to upgrade my fuel lines. Like I said the 92 has a fairly fresh rebuild on the engine and trans and obviously just looks newer all around. So on one hand I have the 84, which I like the body style better and may handle the wvo (much?) better? and on the other hand I have the much fresher (cosmetically and mechanically) 92 300D 2.5 turbo. Any more thoughts?
