I was doing some reading at Barnes and Noble, picked up this Bible of a book, with every import car from like 1940 to present. Every make and model was written up... Well, I looked up 1985 Mercedes Benzes, and came across some interesting changes. It says the hp was bumped from 123 to 125 for the 300DT(everyone knows that) but explained the increase "due to a change in measurement, no mechanical enhancements" Is this true? Thought the 85 models had different injection pumps and the like...
