The lex garages project was conceived as a study to shed new light on the problem of vehicle operating costs. Hitherto, the only source data on these costs had been the aa schedule. In 1967, vehicle contracts ltd, a subsidiary of lex garages, supplied to the ministry of transport various data on about 1000 hired cars. The data contained details of the make, model and engine capacity of each vehicle and information concerning the length of hire, mileage covered and costs of repairs and servicing. Using these data, regression calculations were made with the total costs during the 'life' of the car as independent variable and the total mileage and the duration of the period of measurement as independent variables. It was found that the average mileage cost excluding fuel and depreciation are in the region of 0.8d per mile and that about 0.1d per mile should be added to this to allow for depreciation. Appendices are given showing full details of the regression results. /TRRL/
