You've got over 500,000 on your '91 350SD, I've got 512,000 on my '91 350SD. We're probably in the top five of the highest mileage vehicles on this forum. Isn't it ironic, you so much as mention any 350SD or 350SDL and you see an immediate negative response, rod bender, worst diesel engine ever made by Mercedes, Mercedes loses class action lawsuit, response, and here we are with a couple 500,000 mile vehicles! Not that I'm disputing, any of the claims against the 350 engine. I am not! I just think it ironic, if not funny that the most maligned engine in Mercedes Benz history has two of them making it to 500,000 mile mark.
