Having just bought my second (newer) BENZ, an 85 300D, andgetting ready to tear it down, a friend noted " Dont you ever get bored with Mercedes?Why dont you trya Porsche or BMW?" My feeling is that a Mercedes is best because of
(1) Body longevity, low or no rust (2) Engine longevity (3) Diesel (4) Parts availability at moderate cost (4) Technical info easily available (5) Once rebuilt, low repair need.
To me a Porsche sounds tempermental, expensive, technically hard to master and parts very expensive. Honestly I would try one, but only if the above points were wrong. Can anyone help before I pull my 300TD engine?
