Hardly seems possible, but when I get back from India at the end of November I'll have had the car a year.
So, what have the Costs been over a year?
Fuel:
8000 miles, 25mpg, average £1.20/L = £1600
Road Tax = £505
Insurance:
Fully Comprehensive, agreed value £79,000, no mileage limit and including commuting/business use = £645
Annual Service = £413.39
Total: £3163 = £0.40 per mile.
Quite reasonable, especially allowing for the absence of depreciation.
You could factor in the opportunity cost, that is what could I have got investing £65,000 for 12 months? At best 1.5%, so £975, less 40% income tax, so £585.
Grand total £3748 = £0.47/mile.
Or another way £10.27 per day = A good bottle of wine.
I do not consider running Tarka to be at all costly: the BMW cost more, over 2 years, when depreciation is factored in. And I really didn't enjoy it!
