Used Cars This data is on the asking prices of used Mercedes, classified by several factors. It is taken from the advertising pages of the Sunday Times a few years ago and represent cars for sale in the UK (mainly in and around London) in pounds. The asking prices are classified according to type/model of car, age of car (in six-month units based on date of registration), recorded mileage, and vendor. Interest lies in explaining price, distinguishing models according to price, depreciation with age and mileage, possible varying depreciation rates across models of car, collinearity issues for age and mileage, possible vendor differences on asking prices, outliers, influential cases, and predicting prices.
