Today is my 2nd anniversary of taking ownership of my Jazz, so I topped off the tank and worked out my numbers for this year, and since buying the car.
This year I have covered 8910 miles, which works out at 171 miles per week. I have used a total of 161.3 gallons of petrol which calculates out at an average of 55.2 mpg over that distance. Cannot get much more accurate than that.
Total cost was £2,374.22, which covers fuel, tax, insurance, servicing, repairs, parking, polish, shampoo, odd car wash and of course, by gearbox repair. That works out at £45.66/week or 27p/mile.
I don't figure depreciation in my costs, as I buy an old car and run it until it is finished. I do calculate the cost per mile for the running total, including the purchase price, and it currently stands at 38p/mile. That of course reduces, the longer I keep the car.
Overall I am pleased with these numbers.
