Maybe this is geeky or maybe I am wrong, but I worked as follows and somehow think there is a mathematical miscalculation in the fuel prices, maybe someone needs to verify and write to the fuel stations if I am right, do you agree? Peugeot HDi engine consumes 9.3 liters per 100 km The road to work is 6.5 km to 6.9 km each way, i.e. 13.8 km excluding personal trips and inefficiencies such as being stuck in traffic. Fuel prices Petrol is 1.44 EURO per litre Diesel is 1.36 EURO per litre Enemalta plc | Fuel Price Revisions: May 2014 – December 2014 They have not been revised in a while. Therefore if I travel to work daily I would consume 6.42 litres × 1.36 EUR = 8.73 EUR, whereas by bus I get charged at 0.25 EUR [omissions and errors add to the cost of travel and punctuality is a problem openly complained about in industrial relations as a matter that is beyond one's control]. Is there a mistake in my calculation? I think the consumption is too low; maybe I have not yet estimated the servicing, which is around 100 EUR to 200 EUR every three months based on estimates of previous car servicing.

It all depends on what is being considered in the term "consumed." Tires wear out. Lubricants must be replaced. Eventually the car itself gives up the ghost. Over the life of the car, the initial cost to purchase the car, the cost of periodic maintenance, and the weekly cost of gasoline all must be considered. Which of those the dealer was talking about is unknown so the statement is virtually meaningless despite its apparent quantification.
