by most car manufacturers today, but now only GM and Chrysler produce the "push-rod" variant with any regularity. Since overhead cam engines are design variants of OHV engines, it is fair to classify virtually all modern engines as derivatives of Buick's invention. The money ran out again, and in 1903 Buick was forced to raise more money via a $5,000 loan () from a friend and fellow car enthusiast, Benjamin Briscoe. With this financial help, Buick formed the Buick Motor Company, which would eventually become the cornerstone of the General Motors empire. Later life and business failure In 1906, Buick accepted a severance package and left the company that he had founded, with only one share of the company in his possession. Then president of Buick, William C. Durant, bought this share from him for $100,000 (). After unsuccessful investments in California oil and Florida land, and an attempt (with his son Tom) to manufacture carburetors, Buick made a brief return to the automotive business in 1921, as president of the short-lived Lorraine Motors, and in 1923 with the design of the Dunbar, an automobile prototype. In an interview with historian Bruce Catton in 1928, Buick admitted that he was almost completely broke, unable to even afford a telephone, and worked as an instructor at the Detroit School of Trades. He died of colon cancer on March 5, 1929, at the age of 74 and was buried at Woodmere Cemetery in Detroit, Michigan. Commentator Theodore F. McManus noted that "Fame beckoned to David Buick. He sipped from the cup of greatness, and then spilled what it held." In 2000, automotive historian Vincent Curcio observed that "To date, over 35,000,000 motor cars have been built in his name, which will never be lost to history." He was inducted into the Automotive Hall of Fame in 1974.
