I second the statements from 64biscayne. My daily driver is a '79 Mercedes 300CD w/265,000 miles on the inline 5 diesel. It uses no oil between changes, runs like a top, and will probably reach 400/500,000 miles before it dies. Another great inline engine in my opinion is the Mercedes 280, hemi head gas 6 cylinder made from the late 70's to the mid 80's. They are fuel efficent, long lasting and FAST!!!
