I've just put all the costs for my 318iS into sprintmonitor.de..
The car has been on the road since 1st February 2011, and replaced my Saab 9-3..
So far I've covered 5472 miles, and used 134 UK Gallons..
that's
40.8 UK MPG including a trackday
Including the purchase cost of the car and Tax, the total running costs come out at
£0.26 per mile
meaning my daily commute costs me £13 for 50 miles.
taking off the purchase price and tax (car was bought outright and is old enough not to be affected by depreciation) makes my daily commute
£7 return.
This is £2.50 LESS than the train would cost to get there.. so I save £12.50 a week, PLUS about 8hrs travel time
Gawd bless Ecomodder
Now i'm onto my e30 320i, and initial results are promising- my good lady has taken over the iS and is being pestered to continue hypermiling
