Owners of cars do not usually bother much about running

costs, with the result that data of this kind are not very often available. Such as there are make it plain that where a motorist buys a good car in the first place and treats it in a reasonable way, costs work out less than is often imagined. Here are some figures relating to three years' running of four 14 h.-p. Armstrong-Siddeley cars used to maintain a service between various works and offices of a large commercial undertaking. Cars Nos. 1, 2 and 3 are fitted with landaulette bodies, while No. 4 is a saloon. For 1928 total mileage of the four machines was 51,554, and the cost per mile under the various headings was : petrol, .62d. ; oil, .04d. ; repairs, .11d. ; tyres, stores, and general, 1.27d. These give a total of 2.04d. per mile. This does not include wages of chauffeurs or depreciation. The cost of repairs is low. No. 1 from May 1925 to December 1928 cost £48 3s. 9d. ,• No. 2 from July 1925 to the same date £18 14s. 3d. ; No. 3 from April 1926 to the same date £2 10s. 7d. • and No. 4 from July 1926 to December 1928 only 19s. 9d. Tyres are, of course, not included in these totals.
