Show i Average Life of Auto Has Definite Increase A study made some years aero by C. E. Griffin, professor of marketing at the University of Michigan, gave the average life of motor vehicles generally as 7.04 years, with a definite defi-nite though not a steady Increase from year to year. The replacement demand was claimed to be showing a marked Increase, both absolutely and relative to the total demand, and was predicted at over 2,000.000 for 1927 and 'over 2,340,000 for 192S. The rate at which automobiles of a given years production are eliminated from use was given as follows: of any 100,000 cars placed In use, 75 per cent will still be in use at the end of 4.75 years, 50 per cent at the end of 6.94 years, and 25 per cent at the end of 9.2 years. This study was made about ten years ago. Recent figures by the National Automobile Chamber of Commerce show for 1931 a production pro-duction of 2.3S9.73S, of which 2.14S,-917 2.14S,-917 were for the domestic market; the number scrapped was 2,SS0,095 and those listed as scrapped or replaced re-placed 2,14S,1S1, leaving a 1931 registration reg-istration in this country of 25,S14,103.
